06/16/2025, 9:14 AMDo I need to be subscribed to Eleven labs?
ivy
06/16/2025, 9:15 AMi was advised not to do that as I will be running 18K++ phone calls so to avoid latency issue I was told to use Vapi's connection as you guys get priority

06/16/2025, 9:17 AMYes, you need an 11Labs account with an API key to use their voices in Vapi, but a paid subscription isnât required unless you exceed the free tier limits..

06/16/2025, 9:54 AMHow do I add the voice selection using Vapi's eleven labs account?
ivy
06/16/2025, 9:55 AMI wanted to have that drop down option for selection of voice available on dashboard
ivy
06/16/2025, 9:55 AMbecause we need to get the Voice ID but the dashboard only showing name of the voice not the voice ID

06/16/2025, 10:02 AMFirst add your 11Labs API key in your Vapi dashboard to sync your voices, then go to the âVoicesâ tab under Assistants, find the voice by name, and view or extract its voiceId often visible in JSON/config view or when selecting the voice, which you can then set in your assistantâs configuration using the "voice": { "provider": "elevenlabs", "voiceId": "your-voice-id" } format..

06/16/2025, 9:29 PMThank you. Last question which voice available currently can be used for Thai language?

Kings_bigðŦ
06/16/2025, 9:32 PMUse Azure voices like th-TH-PremwadeeNeural, th-TH-NiwatNeural, and th-TH-AcharaNeural, which can be selected in the Voice settings of your assistant..

However, when we run call using Twilio, we get this error "An error occurred in this call: pipeline-error-eleven-labs-voice-not-found". We are not sending any 11labs info in our request payload (see below - snippet)
