Function "SLN_ASR_LOCAL_Process" return "kAsrLocalUnsupported"

[JosephHsu]

I use iMXRT106s with local voice function, and hit a issue that function "SLN_ASR_LOCAL_Process" always return value 2 which means "kAsrLocalUnsupported". But I have no idea what's wrong with the status, could you help to give more information about this?

Hi @JosephHsu,

This return value means that the ASR engine is detecting an unsupported MCU. The RT106S is of the MCU-LOCAL2-VOICE is no longer recommended for new designs. Please look into the newer SLN-SVUI-IOT for more information about supported voice solutions based on the i.MX RT family.

BR,
Edwin.
