Summon by name
Wake words like “Hey Planner”, “Researcher” or “Builder” route your question to the bot you named.
Summon your whole team of bots in one call.
Stay in control of your team with one voice.
Call a meeting and your whole bot team shows up live, each one in its own voice. Toss out an idea, and watch them pick it up, build on it, and hand it back better, all while you run the room.

What is Voice Blender?
One live call. Your whole bot team. Every bot with its own voice.
Voice Blender lets several AI bots take part in one live voice conversation. You call a bot by name, like “Hey Planner”, and that bot’s reply is spoken in its own dedicated voice.
A turn-taking mixer blends the bots’ voices so they don’t talk over each other or over you. It listens for acoustic cues like pauses and pitch drops, not just text signals, to decide when someone has finished speaking.

Planner
- You Hey Planner, help me plan my week.
- Planner Sure. What’s on your list?
- You Researcher, what do you think of this idea?
- Researcher Here’s what I’d add.

- Builder Here’s the next step.
How it works
Talk once. The right bot answers.
Here’s what happens on a call, step by step.
-
1
Start a call
Open one live voice call. Your bots join the same call, each as its own speaker.
-
2
Say a bot’s name
A wake-word listener hears names like “Hey Planner” or “Builder” and hands what you say next to that bot.
-
3
The bot thinks
The named bot writes its reply with its own persona, memory and tools.
-
4
It answers in its own voice
The reply is spoken in that bot’s dedicated voice, but only when the turn-taking mixer gives it the floor.
-
5
Long text goes on screen Next build
Links, commit hashes, drafts and code show up in a copyable panel instead of being read out character by character.
Features
Why a blender, not just one bot?
Many bots in one call only works if they sound different and don’t talk over each other. That’s the whole idea.
A voice for every bot
Each bot has its own dedicated text-to-speech voice, so you can tell who’s talking without looking.
Turn-taking mixer
Bot speech is queued so only one voice talks at a time. Silence length, falling pitch and energy drops tell it when a speaker is done.
Stay in control with one voice
Barge-in: when you start talking, bot audio stops or ducks so you’re never talked over.
Attribution & proof
Built-in attribution and proof features, such as OpenTimestamps stamping. Part of the Symphony plan.
On-screen text Next build
Copyable text during the call, with a short spoken summary like “I put the commit hash on your screen”, plus a history for the session.

FAQ
Questions, answered.
What is Voice Blender?
A way for several AI bots to share one live voice call. You call a bot by name, it answers in its own voice, and a turn-taking mixer makes sure the bots don’t talk over each other or over you.
How does a bot know I’m talking to it?
Wake words. A listener picks up bot names in what you say, like “Hey Planner”, “Researcher” or “Builder”, and hands the question that follows to that bot.
Won’t the bots talk over each other?
That’s what the turn-taking mixer is for. It queues bot speech so only one voice talks at a time, and uses cues like silence length, falling pitch and energy drops to tell when a speaker has finished.
Can I interrupt a bot?
Yes. When you start talking, bot audio stops or ducks. You stay in charge of the call.
How many bots can join one call?
It depends on the plan: one bot on Yap (plus a 2-bot taste for 10 minutes a month, so you can hear the blender), up to three on Chorus, and up to five of your own bots on Symphony.
How do minutes work?
Each plan includes call minutes every month: 30 on Yap (up to 10 a day), 300 on Chorus and 400 on Symphony. Minutes reset monthly and don’t roll over. You’ll get a heads-up at 80%. When you hit the limit, the call stops, unless you’ve turned on extra minutes (10¢/min on Chorus, 15¢/min on Symphony) and set your own spending limit. No surprise bills. Yap’s 10 minutes of 2-bot calls count inside its 30 free minutes. Yap has no extra minutes; upgrade to keep talking.
Can I save by paying ahead?
Yes. Chorus is $24 a month, or $69 for 3 months, $129 for 6 months or $240 for a year ($20 a month). Symphony is $59 a month, or $168 for 3 months, $318 for 6 months or $590 for a year (about $49 a month). That’s up to 17% off.
