ElevenLabs Voices
The IVR Builder connects to Eqho’s shared ElevenLabs account, letting you generate professional AI voice clips for IVR prompts without leaving the app.
Generating a Voice Clip
- Open any audio field and click the AI Voice tab
- Search for a voice — you can browse Eqho’s account voices or search the ElevenLabs community library
- Type your prompt text — this is what the voice will say
- Adjust settings if needed (see below)
- Click Generate to hear a preview
- Click Use This Audio to upload it to Twilio and use it in your flow
Voice Settings
You usually don’t need to change these, but they’re available for fine-tuning:
| Setting | What it does | Default |
|---|---|---|
| Stability | Higher = more consistent tone. Lower = more expressive. | 50 |
| Similarity Boost | How closely the output matches the original voice sample | 75 |
| Style | Amplifies the voice’s natural style | 0 |
| Speed | Playback speed (0.5x to 2.0x) | 1.0 |
For IVR prompts, the defaults work well. If a voice sounds too flat, try lowering stability slightly. If it sounds too wild, raise it.
Team Favorites
You and your teammates can favorite voices to help everyone find the best ones:
- Click the heart icon next to any voice to favorite it
- Favorited voices show a count of how many team members have favorited them
- Sort by Popular to see the team’s top-rated voices first
This helps build a shared library of go-to voices for client IVRs.
Tips
- Bilingual prompts — ElevenLabs produces much more natural bilingual audio than Twilio’s built-in TTS, especially for Spanish
- Preview before committing — Always listen to the generated clip before uploading. If it doesn’t sound right, tweak the settings and regenerate
- Re-generate freely — You can generate as many previews as you want before choosing one
- ElevenLabs voices vary — Some voices handle certain accents or tones better than others. If one voice doesn’t work, try a different one
