Product description

Voice Fans Control Board

 

product features:

 
1. Speech Acquisition Module The speech acquisition module mainly performs functions such as signal conditioning and signal acquisition. It converts the original speech signal into a speech pulse sequence. Therefore, this module mainly includes signal processing processes such as acoustic/electrical conversion, signal conditioning, and sampling.
2. The main function of the speech pre-processing module of the speech pre-processing module is to filter the interference signal, extract the speech feature vector, and quantize the extracted speech feature vector into a standard speech feature vector. Therefore, the module mainly includes speech preprocessing and features. Extraction, vector quantization, and other speech signal processing.
3. The main function of the speech training module's speech training module is to perform probability statistics on multiple collections and extracted speech feature standard vectors, and extract the speaker's best speech feature standard vector to prevent extraction features due to factors such as mood and environment of the speaker. Inaccurate parameters affect the effect of speech recognition. Therefore, the module mainly includes probabilistic statistics, parameter evaluation and other processing processes, and is implemented using a hidden Markov model (HMM model).
4. The main function of the speech recognition module speech recognition module is to compare the re-acquired standard speech feature vector with the speech model in the speech template library to determine the current speech command function. Therefore, the module mainly includes two processes of vector comparison and parameter evaluation. .
5. The voice prompt module The main function of the voice prompt module is to prompt the user to perform related operations or explain the currently completed functions according to the results of voice recognition. Therefore, the module mainly includes voice processing for prompting voice resource files, D/A conversion, and signal amplification. process.
 6. Output control module The main function of the output control module is to output the corresponding control signal according to the result of voice recognition, and to realize the voice control function of electric appliances, televisions, fans and other office appliances. Therefore, the module mainly includes the signal driver, the output controller and the Control object.
7. Speech Template Library The main function of Speech Template Library is to store the best standard speech feature vector after training.
