The STT when French is defined as the language on the call is horrible and full of mistake. English STT is top-notch with only few misunderstanding but doesn't affect the overall call. However, French STT picks up the wrong word, transcript is full of mistake and really affects the overall call experience. I've set the agent to use the 'optimize for accuracy', and it was still horrible. What can be done?

I can help with this! French STT struggles more than English with accents and audio quality. Quick question: What STT service/provider are you using, and are your callers speaking with regional accents (Quebec, Belgian, African French)?

I made sure to use French Canadian language + optimize for accuracy + noise cancelling and background noise removal. This is the setup I have. But I don’t have the name of Retell STT providers. Also, indeed, it is Quebec Accent.

Thanks for clarifying your setup! I understand the challenge French STT, especially with Quebec accents, can be tricky even with Azure’s “optimize for accuracy” and noise cancellation. I have experience fine-tuning STT configurations and can help improve the transcript quality so it better handles regional accents and reduces mistakes. I’d be happy to work with you on this and get it performing closer to your expectations. If you like, we can set up a quick session to review your current setup and adjust the parameters for best results. Looking forward to helping!
