TMDX5535EZDSP: Running TIesr Speech Recognition at 16 kHz

Peman Montazemi

Part Number: TMDX5535EZDSP

Hi,
The TIesr speech recognition that runs on the TI eZdsp C5535 is currently set to use a sampling frequency of 8 kHz. For increased quality of speech recognition, I would like to increase the sampling frequency from 8 kHz to 16 kHz. To this end, what are the needed changes to what parameters in the TIesr code base using Code Composer Studio?

Your precious help is much appreciated.

Best,
Peyman

Hi,

I've notified the sw team. They will post their feedback directly here.

In the mean time, could you share which SDK version are you using?

Best Regards,
Yordan

Peyton,

Unfortunately, 16Khz sampling isn't supported in TIesr.
We recommend customers to use the Sensory Truly Hands Free engine if they want o build a production quality speech trigger product, with support.
A 30 day free trial of the Sensory THF is available here for evaluation software-dl.ti.com/.../index_FDS.html

Hi Yordan,
I am using the c55xCSL-Lowpower version v3.08.00 released by OCT 13 2017.

Thanks,
Peyman

Some of the parameters in the TIesr engine can be changed for it to work at 16 kHz. It would be really helpful to provide those parameters to me instead of pushing me to use a licensed product under a third-party that will charge me an arm and a leg for just a speech recognition engine.

Best,
Peyman
