Voice Recognition Solution with Echo Cancellation and Noise Reduction

[Jack-Cha]

Hi NXP.

Please recommend a solution in the iMX 8M/9 series for voice recognition and noise reduction or cancellation. It is difficult to check the external audio codec in the reference, so is it possible to implement functions such as voice recognition and noise removal with 8MP or 9 series of built-in NPU?

Application is Smart Intercom based on i.MX 8MP or 95 device. Firstly customer would like to begin development with 8MP for now.

Hi Sanket.

Thanks for your kind answer.

Can you please also recommend about Echo Cancellation on 8MP and 95?

The customer firstly look into 8MP, then move to 95 later.

8MP seems have internal DSP. But 95 does not. The application is Doorlock Intercom based on MPU.

Thanks.

Hello @Jack-Cha ,

I hope you are doing well,

->As of now there are no other references available for imx93 & imx8mp for echo cancellation.
Because imx93 is in the pre-production stage.

One can refer to this link for reference only.
