Can the RT600 4mic achieve real-time audio streaming and speaker separation?

We are currently using the NXP RT600 for a video project. Does this chip have noise reduction, speaker recognition,
and real-time speech streaming capabilities?

Because I downloaded your example package, the only relatively complete functions are speech
loops, speech quality enhancement, and local speech recognition.
However, this has nothing to do with what I mentioned above. Specifically,
how do we contact your technical support team
about this? An email might provide a more detailed description of my problem and needs.

Dear @isdin909 ,

Thank you for your question about the RT600's audio functions.

Audio function description of the I.MX RT600:

1. Noise Reduction support
The RT600 supports AI/ML noise reduction, primarily through the following two methods:
a. Conversa Voice Suite: Includes machine learning-based noise cancellation (MLNR) to effectively remove non-speech noise such as keyboard clicks, dog barks, and alarm sounds, while also providing full-duplex echo cancellation (AEC) and adaptive multi-microphone beamforming. This solution supports the RT600 (HiFi4 DSP), but is commercial licensed software (requires payment).
b. AI Noise Reduction (Standard Module): NXP also offers a standalone AI noise reduction module that can be deployed on the RT600.

2. Speaker Identification Non-native support
The RT600 does not have built-in speaker recognition software. Speaker recognition functionality requires integration with third-party software, which presents licensing challenges.

3. Real-time Audio Streaming support The
RT600 supports real-time audio streaming. On the hardware side, the HiFi4 DSP achieves low CPU usage audio data transmission via DMA + I²S/SAI interfaces; on the software side, Conversa supports full-duplex real-time voice calls (VoIP) and is Microsoft Teams certified.
In addition, the RT600 also supports wireless audio streaming (A2DP/HFP) via Wi-Fi/BT modules (such as the IW611).

Regarding how to obtain technical support:

1. Voice & Audio Dedicated Email (Highly Recommended)
For inquiries about advanced voice and audio features such as Conversa and speaker recognition, please email: [email protected]

This is the dedicated email address for the NXP Voice & Audio R&D team. You can describe your project requirements in detail (noise reduction, speaker recognition, real-time streaming) and they will assess whether to provide a Conversa license or a customized solution.

2. NXP Technical Support Portal (Submit a Support Ticket)
Log in to support.nxp.com to submit a Support Ticket, select the product i.MX RT600, and you can attach a detailed requirements description document.

3. NXP Forum Community
