Description

It is a kind of to change the device and method for waking up word in real time
Technical field
The present invention relates to field of speech recognition, especially relate to a kind of combine offline and online speech recognition technology Novel voice identification equipment and method.
Background technology
Speech recognition at present is widely used in each electronic product as a kind of conventional human-computer interaction technology, with Its naturally convenient interactive mode receives liking for consumer, has been increasingly becoming the main flow interactive controlling side in intelligent artifact epoch Formula, current speech recognition product facility can by the way of word is waken up, i.e., speech ciphering equipment normal use when be in standby shape State, the voice in environmental noise and user's normal life will not be responded.Only user is being told to equipment using voice During the wake-up word pre-defined, speech ciphering equipment can be just waken up, starts that processing is identified to extraneous voice signal.So doing can To reduce the misrecognition of speech recognition apparatus, widely used in current Related product equipment, this method is in the application There are problems that, be to be cured to by producer before dispatching from the factory in product facility due to waking up word, user can not change, therefore be difficult to full The demand that sufficient user personality customizes, if unique user family has bought the speech recognition apparatus of multiple same models simultaneously, if These equipment all there is identical to wake up word, may be caused when user wakes up by the equipment for being not desired to wake up to false triggering Puzzlement in use, this just needs to provide a kind of mode for allowing user voluntarily to change wake-up word, to meet the needs of client, Some current speech recognition apparatus can allow user to input the wake-up word that user wants by recording, then directly against the recording To identify, but which be only capable of it is effective to the user of recording, when substitution is waken up, often because everyone phonetic feature Difference, individually comparing the mode of the wake-up word phonetic feature of recording can cause to wake up failure, reduce the experience sense of user.
Wake up word and can to solve the above problems, needing to invent a kind of can freely change and make the wake-up word of change not by spy The real-time replacing for determining the limitation of people wakes up the apparatus and method of word.
The content of the invention
A kind of to change the equipment for waking up word in real time, it includes:
Speech signal collection processing module, the speech signal collection processing module gather voice data, and to the sound number According to being handled;
Voice wakes up control module, and the voice wakes up control module and is attached simultaneously with the speech signal collection processing module Receive the voice data come from speech signal collection processing module transmission;
Speech recognition and network transmission module, the speech recognition and network transmission module wake up control module pair with the voice To connection;
High in the clouds training server, the high in the clouds training server carry out two-way company with the speech recognition and network transmission module Connect.
As the preferred scheme of the present invention, the voice wakes up control module internal storage space and places what is pre-set Word is waken up, the voice wakes up control module and decodes the speech data, and identifies whether the speech data is the wake-up Word, the voice wake up control module and are combined the institute that can actively change in the memory space with the high in the clouds training server State wake-up word.
As the preferred scheme of the present invention, the voice wakes up control module and controls the speech recognition and network transmission mould The open and close of block, when the speech signal collection processing module judges the voice data to wake up word, the voice Identification and network transmission module are opened, on the contrary then close.
A kind of to change the method for waking up word in real time, it comprises the following steps:
The extraneous voice signal of step 1 speech signal collection processing module collection;
Speech signal collection processing module described in step 2 carries out noise reduction to the voice signal and enhancing processing forms new language The new voice signal is simultaneously sent to voice wake-up control module by sound signal;
The control module that voice described in step 3 wakes up detects whether the new voice signal is effective wake-up word, is effectively to call out Awake word then enters in next step, is not effective wake-up word then repeat step one;
Voice described in step 4 wakes up control module and opens speech recognition and network transmission module;
Speech recognition described in step 5 and network transmission module send hint instructions, remind user to send instruction;
The real-time voice of speech signal collection processing module collection user instructs and is sent to the speech recognition described in step 6 And network transmission module;
Speech recognition described in step 7 and network transmission module detect whether the real-time voice instruction is effective Voice command Instruction, corresponding control operation is performed if real-time voice instruction is effective phonetic control command, if the reality When phonetic order be that invalid phonetic control command then terminates operation, waken up if real-time voice instruction is preset change The instruction of word, then enter in next step;
Step 8 user inputs the new wake-up word to be changed according to prompting, and the speech signal collection processing module is gathered and located Manage the new wake-up word;
Speech recognition described in step 9 and network transmission module receive the institute come from speech signal collection processing module transmission New wake-up word is stated, and sends the new wake-up word to high in the clouds training server;
High in the clouds training server described in step 10 is handled the new wake-up word, and the high in the clouds training server is by described in The new word that wakes up is converted into text, and the speech model transferred according to the text by big data training generates the user's request Wake-up word, then by it is described wake-up word be transferred to the speech recognition and network transmission module, the wake-up word of the user's request The wake command of unspecified person can be realized;
The wake-up word of the user's request is transferred to the voice and called out by speech recognition described in step 11 and network transmission module Awake control module, the voice, which wakes up control module and is written to the wake-up word of the user's request in built-in memory space, to be covered Lid falls original wake-up word, realizes the replacing for waking up word.
Compared with prior art, beneficial effects of the present invention:
The present invention can allow user directly to use the self-defined required wake-up word of voice, and be ensured by way of big data training The wake-up word can realize the wake-up of unspecified person, improve the usage experience of user independent of some particular person after change Sense.
