Hi team, In the last few days I’ve been getting very low-quality voice output when using Vapi. The audio comes out glitchy — sometimes overlapped, with cuts or jumps mid-sentence. This seems to happen across all voices. I tested ElevenLabs specifically because I can also run those voices directly through their platform, and there the audio is smooth and consistent. The issue only appears when running through Vapi. It was working fine a few days ago, so it feels like something recently changed on Vapi’s side. Has anyone else run into this, or is there an update I should be aware of? Thanks! Some call ids: 87a604b5-0643-4c20-a06f-d047320d2301 - at 00:26 c8acdd79-d9c5-424e-89e5-3a8ef19667ed - 00:08 to 00:11

Suggestion: To diagnose the glitchy voice output, review the affected call in the Vapi dashboard: 1. Go to

Observe > Call Logs

in [dashboard.vapi.ai](https://dashboard.vapi.ai/). 2. Search for your call ID (e.g.,

87a604b5-0643-4c20-a06f-d047320d2301

). 3. Check for error messages or anomalies in the transcript and audio logs. If you spot issues, include the call ID and timestamp when reporting to support for faster resolution.

Getting the same issue today

Glad (sort of 😅) I’m not the only one. Has anyone else run into this? Curious if it’s widespread or maybe region/setup-specific. Also, if anyone’s found a workaround, would love to hear.

Nosotros nos ocurre lo mismo con todos los bots que tenemos activos.

Recientemente? A mí me estaba funcionando perfecto la semana pasada.

Nos hemos dado cuenta desde ayer, lunes. Entiendo que recibimos las actualizaciones de Vapi semanalmente, por lo tanto, si el viernes estaba funcionando y el lunes no, es porque Vapi ha realizado algún cambio que ha tenido un impacto. He notado que el JSON de respuesta de la llamada está formateado de manera diferente, detectando cada palabra del cliente a través del transcriptor. https://cdn.discordapp.com/attachments/1422130421122072607/1422489146794053702/image.png?ex=68dcdbc1&is=68db8a41&hm=262d27f411096b95293d4adb85637ecdfb99014a0b5fbd2b17c444981d4b4062& https://cdn.discordapp.com/attachments/1422130421122072607/1422489147108622337/image.png?ex=68dcdbc1&is=68db8a41&hm=3a5a344ce383b94f9e3481f895ffdaf896b5682dd7c5879d39c5c1080d0c12d3&

We are getting the same issue! I hope on a fix very soon!

Yes, still happening. Very very frustrating.

following thread

It seems it's fixed now.

as well for us

I've been having this issue for past 3 weeks. I have a major 6 figure contract now in jeopardy because the voice suddenly started cutting out or skipping mid sentence, along with weird vocal pitch surges here and there. Client now wants to wait until these issues are resolved and confidence is impacted. I've wasted close to 40 hours trying to debug this. @Sam have you seen a full resolution of this issue? I just tested today and was still experiencing glitches.

Could you please provide a call id?

Update from the origina issue from this thread - I was able to resolve it by changing the voice config model from ElevenLabs Turbo v2.5 to v2. Difference being v2.5 is multilingual while v2 is english only. Saw some documentation online saying v2 may have better performance, working for our team so far

Sounds good. Let us know if you encounter any issues with it
