Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defect that the existing technology can only analyze the voice semantics on the server side when performing voice interaction, and the accuracy of the analysis is completely dependent on the server, so that the analysis results cannot be applied to the device side, and provide a terminal device and its voice interaction method

Embodiment 1

[0071] This embodiment provides a voice interaction method for terminal equipment. The voice interaction method acts on the terminal device, and can realize human-computer interaction between the user and the terminal device. The terminal device can be any device, including but not limited to smart home devices, smart home appliances, and especially smart kitchen appliances (such as range hoods, stoves). In addition to the hardware and software structure that realizes its original functions, the terminal device may also have a voice receiving module (such as a microphone array), a processor, a memory, and components that realize networking functions. The memory may include a volatile memory, such as a random access memory and / or a cache memory, and may further include a read-only memory.

[0072] Such as figure 1 As shown, the voice interaction method of the terminal device may include the following steps:

[0073] Step 101: Receive voice input. This embodiment does not limit th...

Embodiment 2

[0081] This embodiment is a further improvement on Embodiment 1. In this embodiment, the user intentions expressed by the online semantic analysis result are mainly divided into two types, namely: content type intentions and control type intentions. The so-called control intention can indicate that the user wants to control the terminal device, such as causing the terminal device to perform a certain operation (such as turning on or off or other operations determined by the type of terminal device), changing to a certain state ( Such as sleep state, running state or other states determined by the type of terminal equipment). The so-called content-type intent may indicate that the user wants to query certain types of information or feedback on certain specific content on the terminal device. Taking the terminal device as a range hood as an example, the content-type intent may be querying a certain recipe , Have a voice conversation with the user.

[0082] Considering that the an...

Embodiment 3

[0119] The voice interaction method of this embodiment can further realize the local semantic analysis of the terminal device. In order to accelerate the speed of voice interaction, for the voice input that can be parsed by the terminal device, the local semantic analysis can be preferentially adopted. If the voice input exceeds the parseable value of the terminal device For the scope, online semantic analysis is adopted. Such as Figure 4 As shown, the voice interaction method may specifically further include:

[0120] Insert step 1011 between step 101 and step 102: determine whether the voice input satisfies the local parsing condition of the terminal device: if yes, execute step 107, if not, execute step 102. In this embodiment, the local parsing condition may include that the voice input hits a local command word pre-stored in the terminal device. Each local command word can represent a user intention. The user model pre-stored in the terminal device includes different expr...

Abstract

The invention discloses a terminal device and a speech interaction method thereof. The speechinteractionmethodcomprises the steps that a speech input is received; the inputted speech is uploaded to aparsing server for online semantic parsing; an online semantic parsing result fed back by the parsing server is received; according to semantic error correction rules prestored in the terminal device,semantic error correction of the online semantic parsing result is conducted locally in the terminal device to obtain a corrected semantic parsing result; and the corrected semantic parsing result isfed back. According to theterminal device and thespeech interaction method thereof,thesemantic error correction of the online semantic parsing result is conducted by the semantic error correction rules prestored locally in the terminal device, so that the semantic parsing result can be applied to the terminal device, accuracy of speech parsing isimproved, and realization of effective feedback bythe terminal device is facilitated.

Description

Technical field [0001] The invention belongs to the field of voice interaction, and particularly relates to a terminal device and a voice interaction method thereof. Background technique [0002] With the gradual popularization of intelligence in home appliances, how to realize the interaction between devices and people has become a hot topic. Voice interaction has become a common way of interaction. This way is widely used because it does not require manual operation by the user, which helps to improve the user experience. [0003] When an existing smart device performs voice interaction, the device itself often does not have a voice analysis function, and the voice needs to be uploaded to the server for natural language analysis, and then the server returns the analysis result to the device. For this method, the accuracy of voice analysis is completely determined by the analysis level of the server, and the device can only passively receive the analysis result. Generally, serve...
