DSP Engineers, and where to find them?

Dear community,

For a product my company is developing, we are using the ADAU1761 codec and two Wolfson MEMS microphones to eventually do speech recognition. Unfortunately, the audio quality received is not as high as we'd hoped due to the casing.

At the moment we are not utilizing the DSP's features, but piping the analog input directly to the Speech-to-Text engines. This works pretty good <2m distance, but from there the recognition quality drops fast.

At my company we have not much experience with DSP configuration, and frankly, it's not a job that seems to be easily findable. So I'm hoping to find someone who can freelance to help us out.

How would a person that can optimize the DSP's configuration call himself, and where do they usually work?

Thanks a lot in advance,

Emile

Hello Emile,

Try to contact the ADI support in Europe. They should know of some people who can do this work. I know there are some good DSP engineers in Denmark and I think there should be some in the Netherlands as well.

You are probably having noise issues and also issues with reflections in the room that can interfere with a speech to text conversion. Echo cancellation is a rapidly developing field right now so there are people around who will know a lot about this problem. So start with our local office and see what they say. If you get nowhere then let me know and I can try some other avenues for you.

Hello weejewel

We encourage networking among members but feel it is important to note that if you find a freelancer via the EngineerZone network; ADI is not responsible for and does not guarantee any work performed by non-ADI personnel. Please perform the due diligence that you would for any other subcontractor or freelancer that engages with your organization.

Thank you
