Description

Technical Field

[0001] The present invention relates to the field of audio processing technology, and in particular to a voice broadcasting method, apparatus, device and readable storage medium. Background Art

[0002] When performing voice broadcast, it is usually necessary to do so in a good network environment. When the network environment is poor, there may be lag or the broadcast may fail. In order to solve the above problems, the existing technology usually stores the audio to be broadcast in a local cache when the network environment is good. When voice broadcast is required, if the audio corresponding to the voice broadcast has been stored in the local cache, the audio stored in the local cache can be directly used for broadcast. If it is not stored in the local cache, online audio synthesis and broadcast are performed.

[0003] However, as more and more audio is broadcast, this solution will undoubtedly increase memory usage. When the corresponding audio does not exist in the local cache and the network environment is poor, smooth voice broadcasting is still impossible. Therefore, there is an urgent need for a method that does not rely on memory usage and can achieve smooth voice broadcasting both offline and online. Summary of the Invention

[0004] The object of the present invention is to provide a voice broadcast method, device, equipment and readable storage medium, which achieves the effect of reducing memory usage and ensuring the continuity of voice broadcast when the network environment is poor by giving priority to broadcasting online voice audio and, based on the disconnection point, switching from broadcasting online voice audio to broadcasting offline voice audio when the network status at the second moment is in a poor state and the online voice audio has not been synthesized.

[0040] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] It should be noted that references to "one embodiment," "an embodiment," "an example embodiment," etc., in this specification indicate that the described embodiment may include specific features, structures, or characteristics. However, not every embodiment must include these specific features, structures, or characteristics. In addition, such references do not necessarily refer to the same embodiment. Furthermore, when specific features, structures, or characteristics are described in conjunction with an embodiment, whether or not explicitly described, it is indicated that it is within the knowledge of those skilled in the art to incorporate such features, structures, or characteristics into other embodiments.

[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] In some embodiments, as Figure 1 As shown, a voice broadcast method is provided, and the specific method includes:

[0044] S101, when a voice broadcast instruction is received, the network status is monitored in real time.

[0045] The voice broadcast instruction includes a voice broadcast text.

[0046] For example, when voice broadcast is required, the operation and maintenance personnel will send a voice broadcast command carrying the voice broadcast text. After receiving the voice broadcast command, the network monitoring tool can be called to monitor the network status, such as Nagios Core, Zabbix, Icinga2, OpenNMS, Prometheus, Graphite, Checkmk, etc. These tools provide rich functions, including network performance monitoring, fault detection, traffic analysis, etc.

[0047] S102: If the network status at the first moment is in a good state, synthesize the offline voice audio and the online voice audio according to the voice broadcast text, and broadcast the online voice audio.

[0048] In fact, the first moment is the moment when the voice audio is about to be performed.

[0049] Specifically, if the network status at the first moment is in good condition, the online and offline TTS (Text to Speech) services are directly called, the offline voice audio and the online voice audio are synthesized simultaneously based on the voice broadcast text, and the online voice audio is broadcast.

[0050] Optionally, if the network status at the first moment is in a bad state, offline voice audio is synthesized according to the voice broadcast text; and the offline voice audio is broadcast.

[0051] Specifically, if the network status at the first moment is in a bad state, the online voice audio cannot be synthesized. At this time, it is only necessary to call the offline TTS service, synthesize the offline voice audio according to the voice broadcast text, and broadcast the offline voice audio.

[0052] S103: If the network status at the second moment is in a bad state and the online voice audio has not been synthesized, a disconnection point in the voice broadcast text is determined based on the online voice audio.

[0053] The second moment is later than the first moment, and the second moment is any moment during the process of broadcasting the online voice audio.

[0054] Specifically, if the network status at the second moment is in a bad state and the online voice audio has not been synthesized, the complete voice broadcast text cannot be broadcast directly based on the online voice audio. At this time, it is necessary to determine the disconnection point in the voice broadcast text based on the last synthesis point of the online voice audio.

[0055] Optionally, if the network status at the second moment is in a good state and / or the online voice audio is synthesized, the online voice audio continues to be broadcast.

[0056] Specifically, if the network status at the second moment is in a good state, the online voice audio can continue to be synthesized and the online voice audio can be played directly. If the online voice audio has been synthesized, the online voice audio can still be played even if the network status is in a bad state.

[0057] Optionally, the method for determining the disconnection point in the voice broadcast text based on the online voice audio may be: determining the disconnection point in the voice broadcast text corresponding to the end point of the online voice audio based on the mapping relationship between the online voice audio and the voice broadcast text.

[0058] Specifically, the online voice audio and the voice broadcast text have a certain mapping relationship, and the disconnection point corresponding to the online voice audio termination point in the voice broadcast text can be found according to the mapping relationship between the online voice audio and the voice broadcast text.

[0059] For example, when the network is detected to be unavailable, the length of the synthesized online voice audio and the timestamp file of the relationship between the voice broadcast text can be used to know the synthesized length of the current voice broadcast text, and the position of the currently disconnected text can be found through the mapping relationship, which is the disconnection point.

[0060] S104: Play the offline voice audio based on the disconnection point.

[0061] Specifically, according to the mapping relationship between the offline voice audio and the voice broadcast text, the starting point corresponding to the disconnection point in the offline voice audio can be found, and then the offline voice audio can be played from the starting point until the voice audio is played to completion.

[0062] In the above embodiment, when a voice broadcast instruction is received, the network status is first monitored in real time; the voice broadcast instruction includes a voice broadcast text; if the network status at the first moment is in a good state, the offline voice audio and the online voice audio are synthesized according to the voice broadcast text, and the online voice audio is broadcast; if the network status at the second moment is in a bad state, and the online voice audio has not been synthesized, the disconnection point in the voice broadcast text is determined according to the online voice audio; the second moment is later than the first moment; finally, based on the disconnection point, the offline voice audio is broadcast. The above scheme gives priority to broadcasting online voice audio when the network status is good, which greatly reduces the memory usage. Secondly, when the network status is not good, the voice broadcast can be converted from online voice broadcast to offline voice broadcast based on the disconnection point, ensuring the continuity of the voice broadcast when the network status is poor.

[0063] On the basis of the above embodiment, in order to further reduce memory usage, the voice broadcast method may further include: if it is detected that the online voice audio or offline voice audio has been broadcasted, deleting the offline voice audio from the local storage system.

[0064] Specifically, the broadcast status of online voice audio and offline voice audio can be monitored in real time. When the online voice audio or offline voice audio is finished broadcasting, the cache file of the offline voice audio is deleted from the local storage system. That is, each time the voice is broadcast, only one cache file of the offline voice audio needs to be stored, which greatly reduces memory usage.

[0065] In another embodiment, Figure 2 As shown in the figure, the specific process of broadcasting offline voice audio based on the disconnection point is described, including:

[0066] S201: Determine a starting point in the offline voice audio corresponding to a disconnection point according to a mapping relationship between the offline voice audio and the voice broadcast text.

[0067] Specifically, the offline voice audio has a duration, and each word in the voice broadcast text corresponds to the timestamp of the offline voice audio, that is, the mapping relationship between the offline voice audio and the voice broadcast text. The starting point in the offline voice audio corresponding to the disconnection point can be determined based on the mapping relationship.

[0068] S202, when it is detected that the broadcast reaches the end point of the online voice audio, the offline voice audio is broadcast from the starting point.

[0069] Specifically, when the online voice audio is broadcast to the end point, the synthesized online voice audio has been broadcasted, but the broadcast of the entire voice broadcast text has not been completed. At this time, the offline voice audio is broadcasted from the starting point.

[0070] In the solution of the above embodiment, when the network status at the second moment is in a poor state and the online voice audio has not been synthesized, the online voice broadcast can be seamlessly connected to the offline voice broadcast according to the disconnection point, which greatly improves the broadcast continuity when the network status is poor.

[0071] In order to more comprehensively demonstrate this solution, this embodiment provides an optional method of voice broadcasting, such as Figure 3 As shown:

[0072] S301, when a voice broadcast instruction is received, the network status is monitored in real time.

[0073] The voice broadcast instruction includes a voice broadcast text.

[0074] S302: If the network status at the first moment is in a good state, synthesize the offline voice audio and the online voice audio according to the voice broadcast text, and broadcast the online voice audio.

[0075] S303: If the network status at the first moment is in a bad state, synthesize offline voice audio according to the voice broadcast text.

[0076] S304: Play the offline voice audio.

[0077] S305: If the network status at the second moment is in a bad state and the online voice audio has not been synthesized, a disconnection point in the voice broadcast text corresponding to the online voice audio termination point is determined according to a mapping relationship between the online voice audio and the voice broadcast text.

[0078] Among them, the second moment is later than the first moment.

[0079] S306: Determine a starting point in the offline voice audio corresponding to the disconnection point according to a mapping relationship between the offline voice audio and the voice broadcast text.

[0080] S307: When it is detected that the online voice audio ends at the broadcasting point, the offline voice audio is broadcasted from the starting point.

[0081] S308: If the network status at the second moment is in a good state and / or the online voice audio is synthesized, the online voice audio continues to be broadcasted.

[0082] S309: If it is detected that the online voice audio or offline voice audio has been played, the offline voice audio is deleted from the local storage system.

[0083] The specific process of the above S301-S309 can be found in the description of the above method embodiment. The implementation principle and technical effects are similar and will not be repeated here.

[0084] Based on the same inventive concept, the present application also provides a voice broadcast device for implementing the aforementioned voice broadcast method. The implementation solution provided by the device is similar to the implementation solution described in the aforementioned method. Therefore, the specific limitations of one or more voice broadcast device embodiments provided below can be found in the above-mentioned limitations of the voice broadcast method and will not be repeated here.

The above-mentioned scheme gives priority to broadcasting online voice audio when the network status is good, which greatly reduces the memory usage. Secondly, when the network status is not good, the voice broadcast can be converted from online voice broadcast to offline voice broadcast based on the disconnection point, ensuring the continuity of the voice broadcast when the network status is poor.
