user's voice recorded in recordings when he uses his phone is weak (= weaker than the call done from web) so the transcriber can have problems understanding what the user is saying. I checked two phones and I see the same issue with both ones. And I experimented with different transcribers and the problem is the same. So I assume the problem is not with the transcriber but with the strength of voice which is converted to the text. Any idea on how to fix this?

Hey! To help track down this issue, could you share: - The call ID This would really help us figure out what went wrong!

Examples: a7a7b8b8-0383-4ee7-8b77-7e68b2216051, 772f2b2d-1d82-4de1-894b-c610535ad4b4, 7aa6f0d2-7357-40f4-9322-4ac243f9711e

@Igor I have reviewed the call recordings and determined that the issue is not originating from our end, but rather from the telephony. Please provide me with some time to analyze the pcap files and investigate any potential problems.

@Shubham Bajaj as I wrote I checked 2 different phones to be sure that the issue is not caused by my mobile, and I hear that in both cases my voice recorded in the recording is much weaker than the assistant's voice

@Igor I looked into your calls again and the issue to me is not with the voice instead with the transcription and model prompt.

The user speaks in non-english language, which gets converted into english and eventually you loose words. It's best and advisable to use non-english language prompt, transcriber and voice for great results. Let me know your thoughts on this!!

@Shubham Bajaj please see the difference in the strenght of the recorded user's voice here 52db9fdf-5b67-41e7-82ed-9b701b57ec51 (call over the phone), and 0d268843-7ad1-4db0-b866-efb2c3cf2dfe (call over the web). Do you think it has no impact on the transcriber accuracy?

@Igor No, this did not have any impact. If it had, there would not have been any transcription because our speech confidence threshold is greater than or equal to 0.9. For fair consideration, considering about voice strength, you should check with your telephony provider because the strength of your voice over the phone is something that we do not control and cannot influence.
