Hi Xin.gao,

TI can suggest you two types microphone array boards - linear TIDA-01470 and circular TIDA-01454:
www.ti.com/.../tida-01470
www.ti.com/.../tida-01454
both are PCM1864-Based.
Here you can find Audio Pre-processing System Reference Design for Voice-Based Applications:
www.ti.com/.../TIDEP-0077
Also I suggest you Audio Pre-Processing Demo and guide at:
processors.wiki.ti.com/.../C55x_CSL_Audio_Pre-Processing

which will help you to make various audio processing.

Hi Tsvetolin shulev:

Thanks for your reply,

I have implemented microphone array pickup and subsequent audio processing,

I now need to implement the offline voice control function on this basis,

There is no relevant technical document to refer to?

Hi Xin.gao,

Have you considered Audio Pre-Processing Demo linked in my first post? Here is a short description which seems cover your requirements:
The TMS320C55x™ Connected Audio Framework provides a software framework which allows the C55x devices to operate as a USB Audio peripheral. In addition to providing this capability, the framework can be extended by users by the incorporation of audio processing algorithms in the record and playback paths. The C55x Connected Audio Framework also implements USB Human Interface Device (HID) class which can be used to perform functions such as change volume, play, and stop audio.
