Problem with de voice agent (elevenlabs)
I’ve been experiencing the same issue for several months now and still haven’t received a response. Both myself and several others here on Discord are facing this problem. I recently upgraded to the Business plan specifically to get support, but I still haven’t heard back.
Could you please help resolve this issue? I urgently need to put my customer service agent into production.
The problem occurs when the ElevenLabs account is synced — the voice doesn’t play, and there’s no sound. If you check the logs, you’ll see that a conversation is generated, but in reality, nothing can be heard. Choosing the right voice is essential, especially in countries where English is not the native language. We need a voice that better matches our dialect.
Best regards,

Hi there 👋 sorry you’re running into this. Here’s a checklist that usually gets ElevenLabs audio working again:
1. Make sure the ElevenLabs account that’s linked in your workspace is still valid (API key active and not out of credits). You can re-sync at Integrations ➜ ElevenLabs.
2. Open the agent → Settings ➜ Behaviour ➜ Voice.
• Pick the “ElevenLabs” tab.
• Click a voice, hit the ▶️ icon to preview, then press Save.
• Publish the agent once more.
(ref: docs.voiceflow.com → “Select TTS Voice”).
3. Place a test call: if you still get silence, open the call’s Debug Trace in Voiceflow.
• Look for a line like
Docs for reference:

• Voice troubleshooting limits → https://docs.voiceflow.com
"voice": "elevenlabs:…" and an audio_url.
– If the voice value is blank or the URL is missing, the TTS request failed. Try a different ElevenLabs voice or temporarily switch to the Google/Amazon tab to confirm audio can play.
4. Check the common voice limits (concurrency, 30-min max call, 3-min silence cut-off) just in case the call is being dropped early (docs: “Troubleshooting voice”).
Nine times out of ten re-selecting and saving the ElevenLabs voice—or switching to a different ElevenLabs voice—resolves the “no sound” symptom, especially after an account re-sync.
Give those steps a try and let me know how it goes!Docs for reference:

the api key is correct, i have token in my acc
yes same issue. Also, does Voiceflow support the new V3 model?
solved the issue: you need to have the paid plan on ElevenLabs. It may seem simple, but I didn’t know this — not even ElevenLabs, since they had told me that the free version could be tested without any problems or limitations.
