Description of Acoustic Model¶

The acoustic model is a necessary file for speech recognition, which needs to be integrated and packaged into the voice firmware. This document sorts out the names and characteristics of the acoustic models corresponding to our chips. Users can select the appropriate acoustic models according to the chip model, the Flash capacity size supported by the chip or module, and the product application environment. The acoustic model can be selected and downloaded from the language model function module of our voice AI platform.

Chinese acoustic model¶

Model name	Model number	Model size	Model characteristics	Application scenario
Common mandarin Chinese V1_1.3M_V00487	G3-GE-CH-S-V00487.fefixbin3632	1.3MB	Good recognition effect for standard mandarin Chinese	It is generally used in Chinese. The environmental non human noise is lower than 60dB. The equipment itself has no strong vibration, strong noise (motor, etc.), and strong convection. The signal-to-noise ratio is required to be more than 3dB
Common mandarin Chinese V2_1M_V00485	G3-GE-CH-S-V00485.fefixbin3632	1MB	Good recognition effect for standard mandarin Chinese	It is generally used in Chinese. The environmental non human noise is lower than 60dB. The equipment itself has no strong vibration, strong noise (motor, etc.), and strong convection. The signal-to-noise ratio is required to be more than 3dB
Common mandarin Chinese V4_0.6M_V591	G3-GE-CH-S-V00591.fefixbin3632	0.6MB	Large model with good recognition effect for standard mandarin Chinese and noise resistance slightly lower than 1MB, suitable for use when flash is small	It is generally used in Chinese. The environmental non human noise is lower than 60dB. The equipment itself has no strong vibration, strong noise (motor, etc.), and strong convection. The signal-to-noise ratio is required to be more than 3dB
Low Misunderstanding of mandarin Chinese V1_1.25M_V557	G3-GE-CH-S-V00557.fefixbin3000	1.25MB	False recognition is obviously lower than other models, the recognition rate is slightly lower than other models, and the noise resistance is slightly lower than other models	Special for low error recognition of mandarin Chinese
Mandarin for cigarette machine V1_1M_V00546	G3-YJ-CH-S-V00546.fefixbin3632	1MB	It has a strong suppression on the noise of the flue gas turbine and needs to be used together with the noise reduction	Mandarin for cigarette machine
Mandarin for cigarette machine V2_1.3M_V00567	G3-YJ-CH-S-V00567.fefixbin3632	1.3MB	It has a strong suppression on the noise of the flue gas turbine and needs to be used together with the noise reduction	Mandarin for cigarette machine
Mandarin for heating tables V1_1M_V547	G3-QNZ-CH-S-V00547.fefixbin3632	1MB	The recognition of relevant command words in the heating table field has been enhanced; The noise of heating table is strongly restrained; It shall be used together with noise reduction	Mandarin for heating tables
Mandarin for heating tables V4_1.3M_V571	G3-QNZ-CH-S-V00571.fefixbin3632	1.3MB	The recognition of relevant command words in the heating table field has been enhanced; The noise of heating table is strongly restrained; It shall be used together with noise reduction	Mandarin for heating tables
Mandarin for bathroom V1_1.3M_V583	G3-WY-CH-S-V00583.fefixbin3632	1.3MB	It has a strong inhibition on the acoustic noise of bathroom water and needs to be used together with noise reduction	Mandarin for bathroom

English acoustic model¶

Model name	Model number	Model size	Model characteristics	Application scenario
Common English standard V1_1M_V00488	G3-GE-EN-S-V00488.fefixbin3382	1MB	Better recognition of British and American standard English	It is generally used in English.
