Description

Technical Field

[0001] The present invention relates to the field of TTS voice broadcast, and particularly to a TTS voice broadcast method, device, vehicle and computer storage medium. Background Art

[0002] With the development and popularization of computer technology, intelligent technologies such as human-computer interaction provide convenient and fast services in all aspects of people's lives. TTS (Text to Speech) can realize the conversion from text to speech and is an important technology for human-computer interaction in artificial intelligence technology. TTS is widely used in various intelligent terminals, such as in-vehicle intelligent terminals. When the existing TTS performs a broadcast, it usually directly performs a broadcast after receiving a new broadcast message; or, when receiving a new broadcast message, it interrupts the previous broadcast and directly enters the new voice broadcast; or, when receiving multiple broadcast messages, it queues the multiple broadcast messages and broadcasts them in sequence; or, when receiving multiple broadcast messages, it performs a mixed broadcast on the multiple broadcast messages. However, in actual applications, the above processing methods cause the TTS broadcast to be suddenly interrupted, or the broadcast time is too long, or the mixed broadcast is not clear, so that multiple applications using TTS to broadcast simultaneously need to preempt the audio focus, resulting in a poor user experience. Summary of the Invention

[0016] It should be noted that in this document, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements not only includes those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising such element. In addition, components, features, and elements with the same name in different embodiments of the present invention may have the same meaning or different meanings, and their specific meanings need to be determined based on their explanations in the specific embodiments or further in combination with the context in the specific embodiments.

[0017] It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this document, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "when" or "upon" or "in response to determining". Furthermore, as used herein, the singular forms "a", "an" and "the" are also intended to include the plural forms unless the context indicates otherwise. It should be further understood that the terms "comprise", "include" indicate the presence of the stated features, steps, operations, elements, components, items, kinds, and / or groups, but do not exclude the presence, occurrence or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The term "or" and "and / or" used herein are interpreted as inclusive, or meaning any one or any combination. Thus, "A, B or C" or "A, B and / or C" means "any of the following: A; B; C; A and B; A and C; B and C; A, B and C". An exception to this definition only occurs when the combination of elements, functions, steps or operations is inherently mutually exclusive in some way.

[0018] It should be understood that although the steps in the flowchart in the embodiments of the present invention are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps has no strict order limit and can be executed in other orders. Moreover, at least a part of the steps in the figure may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or sub-steps or stages of other steps.

[0019] It should be noted that in this article, step codes such as S101 and S102 are adopted. The purpose is to more clearly and briefly express the corresponding content and do not constitute a substantial limitation in terms of order. Those skilled in the art may execute S102 first and then S101 during specific implementation, etc., but these should all be within the protection scope of the present invention.

[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] See Figure 1 , which is a TTS voice broadcast method provided by an embodiment of the present invention. This TTS voice broadcast method can be executed by a TTS voice broadcast device provided by an embodiment of the present invention. The TTS voice broadcast device can be implemented in a software and / or hardware manner. In this embodiment, the TTS voice broadcast method is applied to an in-vehicle terminal as an example for illustration. The TTS voice broadcast method includes the following steps:

[0022] Step S101: Obtain the current TTS broadcast information;

[0023] It should be noted that the TTS broadcast information is based on the feedback information or instructions obtained by the in-vehicle terminal from the cloud platform, user terminal, or other device terminals, rather than being fixedly set in the in-vehicle terminal, thereby realizing dynamic broadcast according to the vehicle status information. The in-vehicle terminal connects to the user terminal or other device terminals through Bluetooth technology and obtains feedback information or instructions. This is an optional extended function to enrich and enhance the compatibility of the system. If this function is not used, it will not affect the normal operation of the system.

[0024] Step S102: Obtain new TTS broadcast information;

[0025] Specifically, when the currently obtained TTS broadcast information is being broadcast in step S101, there may be a situation where multiple applications need to broadcast the TTS broadcast information simultaneously. At this time, new TTS broadcast information needs to be obtained, that is, the TTS broadcast information that other applications need to broadcast simultaneously.

[0026] Step S103: Perform preset processing on the currently obtained TTS broadcast information according to the new TTS broadcast information;

[0027] Specifically, when the new TTS broadcast information is obtained, that is, when there is a situation where multiple applications need to broadcast the TTS broadcast information simultaneously, it is necessary to process the currently obtained TTS broadcast information according to the new TTS broadcast information so that both the new TTS broadcast information and the currently obtained TTS broadcast information can be broadcast without being affected.

[0028] Step S104: Perform voice broadcast on the currently obtained TTS broadcast information after the preset processing.

[0029] Specifically, perform voice broadcast on the currently obtained TTS broadcast information after the preset processing in step S103.

[0030] In summary, in the TTS voice broadcast method provided by the above embodiments, by obtaining the currently obtained TTS broadcast information and the new TTS broadcast information, then performing preset processing on the currently obtained TTS broadcast information according to the new TTS broadcast information, and performing voice broadcast on the currently obtained TTS broadcast information after the preset processing, the user can obtain complete and concise TTS broadcast information without interruption or mixing, improving the user experience.

[0031] In one embodiment, the performing preset processing on the currently obtained TTS broadcast information according to the new TTS broadcast information includes the following steps:

[0032] When the currently obtained TTS broadcast information has not started to be broadcast, extract the same characters from the currently obtained TTS broadcast information and the new TTS broadcast information;

[0033] Perform merging processing on the extracted same characters.

[0034] Specifically, when the current TTS broadcast information is in the preparation stage for broadcasting, that is, when the current TTS broadcast information has not started broadcasting, the same characters of the current TTS broadcast information and the new TTS broadcast information are extracted, and the extracted same characters are merged. For example, if the current TTS broadcast information is "Opening the window for you, please be careful of pinching your hand by the window", and the new TTS broadcast information is "Opening the sunroof for you", then the same characters of the current TTS broadcast information and the new TTS broadcast information are extracted as "Opening the window for you", and the TTS broadcast information after merging the extracted same characters is "Opening the sunroof, window for you, please be careful of pinching your hand by the window". In this way, when multiple TTS broadcast information needs to be broadcast simultaneously, the same characters of the TTS broadcast information are extracted and merged, enabling the user to obtain complete and concise TTS broadcast information, reducing the duration of TTS broadcast, and enhancing the user experience.

[0035] In one embodiment, the preset processing of the current TTS broadcast information according to the new TTS broadcast information includes the following steps:

[0036] When the current TTS broadcast information is being broadcast, the new TTS broadcast information is merged to the end of the current TTS broadcast information.

[0037] Specifically, when the current TTS broadcast information is being broadcast, that is, when the current TTS broadcast information has already started broadcasting, the new TTS broadcast information is merged to the end of the current TTS broadcast information. For example, if the currently broadcast TTS broadcast information is "Opening the window for you, please be careful of pinching your hand by the window", and the new TTS broadcast information is "Opening the sunroof for you", then the TTS broadcast information after merging the new TTS broadcast information to the end of the current TTS broadcast information is "Opening the window for you, please be careful of pinching your hand by the window, opening the sunroof for you". In this way, when new TTS broadcast information is obtained while the TTS broadcast information is being broadcast, and the new TTS broadcast information is merged to the end of the current TTS broadcast information, the user can hear the complete TTS broadcast information without interruption or mixing, enhancing the user experience.

[0038] In one embodiment, the preset processing of the current TTS broadcast information according to the new TTS broadcast information includes the following steps:

[0039] When the current TTS broadcast information has not started broadcasting, compare the priority of the new TTS broadcast information with the current TTS broadcast information;

[0040] According to the comparison result, preferentially broadcast the TTS broadcast information with a higher priority.

[0041] Here, when the current TTS broadcast information is in the preparation stage for broadcast, that is, when the current TTS broadcast information has not started to be broadcast, the priorities of the new TTS broadcast information and the current TTS broadcast information are compared. According to the comparison result, the TTS broadcast information with a higher priority is preferentially broadcast. For example, when the current TTS broadcast information is obtained as "It is sunny today, 15°C, with a northeast wind of level 3 - 4, a bit cool. It will rain later today...", and the new TTS broadcast information is obtained as "The current vehicle speed is too fast, and the window cannot be opened", at this time, the priority of the new TTS broadcast information is higher than that of the currently broadcast TTS broadcast information, so the TTS broadcast information with a higher priority is preferentially broadcast as "The current vehicle speed is too fast, and the window cannot be opened. It is sunny today, 15°C, with a northeast wind of level 3 - 4, a bit cool. It will rain later today...". In this way, when multiple TTS broadcast information needs to be broadcast simultaneously, the priorities of the TTS broadcast information are compared, and the TTS broadcast information with a higher priority is preferentially broadcast, enabling users to obtain more important information first and further improving the user experience.

[0042] In one embodiment, when the current TTS broadcast information is being prepared for broadcast, comparing the priorities of the new TTS broadcast information and the current TTS broadcast information further includes the following steps:

[0043] The priorities are arranged from high to low as safety reminder, navigation broadcast, vehicle control reminder, multimedia, and other types.

[0044] Here, vehicle control reminders include user - initiated vehicle control, system automatic adjustment (such as air - conditioner temperature, etc.), vehicle - control - type inquiries, etc.; multimedia includes music, radio, video, and each of them includes user - initiated control and prompt - type broadcasts, etc. The priorities are arranged from high to low as safety reminder, navigation broadcast, vehicle control reminder, multimedia, and other types.

[0045] In one embodiment, performing preset processing on the current TTS broadcast information according to the new TTS broadcast information includes the following steps:

[0046] When the current TTS broadcast information is being broadcast, compare the priorities of the new TTS broadcast information and the current TTS broadcast information;

[0047] If the priority of the new TTS broadcast information is higher than that of the current TTS broadcast information, truncate the current TTS broadcast information and insert and broadcast the new TTS broadcast information.

[0048] Specifically, when the current TTS broadcast information is being broadcast, that is, when the current TTS broadcast information has started to be broadcast, the priorities of the new TTS broadcast information and the current TTS broadcast information are compared. Among them, the priorities are arranged from high to low as safety reminder, navigation broadcast, vehicle control reminder, multimedia, and other types. If the priority of the new TTS broadcast information is higher than that of the current TTS broadcast information, the current TTS broadcast information is truncated and the new TTS broadcast information is inserted for broadcast. For example, the current TTS broadcast information being broadcast is "The weather is sunny today, 15°C, with a northeast wind of level 3-4, a bit cool. It will rain later today...", and the new TTS broadcast information obtained is "The current vehicle speed is too fast to support opening the window". At this time, since the priority of the new TTS broadcast information is higher than that of the current TTS broadcast information being broadcast, the current TTS broadcast information is truncated and the new TTS broadcast information is inserted for broadcast as "The weather is sunny today, 15°C, the current vehicle speed is too fast to support opening the window...". In this way, when a higher-priority TTS broadcast information is obtained during the broadcast of the TTS broadcast information, the currently broadcast TTS broadcast information is truncated and the higher-priority TTS broadcast information is inserted for broadcast, enabling the user to obtain more important TTS broadcast information first and further improving the user experience.

[0049] In an embodiment, the step of truncating the current TTS broadcast information and inserting and broadcasting the new TTS broadcast information if the priority of the new TTS broadcast information is higher than that of the current TTS broadcast information further includes the following steps:

[0050] Obtain the punctuation characters of the current TTS broadcast information;

[0051] Truncate at the comma or full stop of the current TTS broadcast information and insert and broadcast the new TTS broadcast information.

[0052] Specifically, when it is necessary to truncate the current TTS broadcast information and insert and broadcast the new TTS broadcast information, it is also necessary to obtain the punctuation characters of the current TTS broadcast information, truncate at the comma or full stop of the current TTS broadcast information, and insert and broadcast the new TTS broadcast information. In this way, truncating at the comma or full stop of the current TTS broadcast information can enable the user to obtain more important TTS broadcast information first while ensuring the semantic integrity of the current TTS broadcast information as much as possible, further improving the user experience.
