Voice Sample Preview and Comparison in Telnyx AI Assistant Builder

AI-Assistant audio player for faster voice sampling

1, Dec 2025

AI-Assistant now includes a unified audio player that reduces the steps required to preview and update voice samples. Developers can cycle through voices, adjust playback, and update sample text without reloading audio.

What’s new

Play and pause control: Start or stop any sample with a single action.
Jump navigation: Move playback 10 seconds forward or backward.
Voice cycling: Switch between available voices with Previous and Next buttons.
Live text preview: See the exact sample text being spoken for each voice.
Auto-regeneration: Updated text applies to all future samples without manual regeneration.

Why it matters

Reduces time spent iterating on voice selection.
Improves accuracy when comparing multiple voice options.
Prevents repetitive manual regeneration steps.

Simplifies testing workflows for multi-voice applications.

Example use cases

Tuning voice selection for IVR or agent personas.
Rapidly reviewing multiple voices in product demos.
Updating script text during agent testing without restarting playback.

Getting started

Open AI-Assistant in Mission Control Portal.
Select any voice and use the audio player to play, pause, or jump through the sample.
Use Previous and Next to compare voices.
Edit the sample text and generate a new version; all future samples will update automatically.
Try it out now in our Mission Control Portal.
