Voice AI meeting bots help teams run calls with less busywork.
Instead of a silent notetaker in the corner, these bots can join Zoom, Google Meet, Microsoft Teams, and more.
They listen. They write down what people say. And in many cases, they talk back.
An API is a simple set of commands one program uses to ask another program to do something. Here, that usually means “send a bot to this meeting link.” So, if you are building a product that needs a bot that joins, listens, and speaks, this guide walks through 4 platforms made for that job.
TL;DR
- Telnyx sends a speaking AI bot into Zoom, Google Meet, Teams, or Webex to listen, talk back, and summarize the call.
- Recall.ai sends bots that record and transcribe meetings, and its Output Media feature lets them speak and show video.
- Meeting BaaS sends a bot into Zoom, Meet, or Teams with one simple request, and that bot can listen and talk back.
- Attendee is an open-source meeting bot API that can bring a webpage voice agent into the call.

1. Telnyx

Telnyx Meeting API helps you put an AI participant into a live meeting. It is built for teams that want one account for listening, speaking, AI replies, and meeting bots.
A Bot That Joins, Talks, And Summarizes
Point Telnyx at a Google Meet, Zoom, Teams, or Webex link, and a bot joins the room right away or at a time you set. While the call runs, Telnyx writes a live transcript with speaker labels, and the bot can speak into the meeting, and on Zoom, Meet, and Teams it can post in the chat too. If barge-in is on, the bot also stops talking as soon as someone starts speaking.
Moreover, you can attach a Telnyx AI Assistant, so the bot can listen, think, and answer questions in its own voice. Then, once the meeting ends, Telnyx can create a summary and action items, or answer your own custom question about the call.
Key Features
- Join four platforms with one API: Send one meeting link and use the same kind of request for Zoom, Google Meet, Microsoft Teams, and Webex.
- Live transcript with speaker labels: See who said what, with timestamps, while the meeting is still going, through Telnyx speech-to-text.
- Speech you control: Tell the bot what to say at any moment. Text plays into the room through Telnyx text-to-speech, and people can interrupt if you allow it.
- AI Assistant in the room: Attach a Telnyx AI Assistant so the bot listens, thinks, and speaks back. In group calls, it needs some extra configuration so it doesn't respond to everyone who speaks.
- Meeting chat: Post messages into Zoom, Meet, or Teams chat, including a short note when the bot joins.
- On-camera presence: Show a still picture as the camera tile, or a digital avatar that moves its lips with the bot’s speech.
- After-meeting notes: Get summaries and action items, and also request decisions, topics, open questions, or custom notes from the final transcript.
- Webhooks and AI tool access: Set a webhook so Telnyx can notify your server when something happens.
Why Choose Telnyx
- One API key covers meeting bots, speech-to-text, text-to-speech, and AI summaries. That means one account, one invoice, and one support thread.
- The bot is a speaking participant, not only a notetaker, which fits products that need voice AI inside the call.
- It is fully managed. You use the Meeting API and read back transcripts, speech, chat, and summaries, without running the bot yourself.
2. Recall.ai

Recall.ai provides meeting bots through a developer API. It focuses on joining meetings and capturing conversation data so product teams can build their own AI workflows on top.
Capture Meeting Data And Speak Through Output Media
With just a meeting link, Recall sends a bot into Zoom, Google Meet, Microsoft Teams, Webex, or GoTo Meeting (in beta), even when your user is not the host. The bot returns recordings, transcripts with speaker names, and other meeting details, and live transcripts can arrive while the call is still going.
For agents that need to talk back, Output Media lets the bot play audio and show video from a webpage you control. So, the bot can listen and respond in real time. On top of that, Recall connects bots to Google Calendar or Microsoft Outlook events. It also offers a Desktop Recording SDK, a ready-made code kit, for recording some calls without a bot in the attendee list.
Key Features
- One meeting bot API: Send a bot with a meeting URL and get audio, video, transcripts, and meeting details across major video platforms.
- Transcripts with speaker names: Get live or after-call text with speaker names, using Recall’s own transcription or other providers.
- Output Media for speaking agents: Stream a webpage’s audio and video into the meeting so an AI agent can listen and respond in real time.
- Separate audio and video per person: Get each participant's audio and video as separate live streams over a secure connection.
- Chat and meeting details: Send and receive chat, and track participant names, join events, screen shares, and other meeting events.
- Calendar and desktop options: Schedule from Google Calendar or Outlook, or record with the Desktop Recording SDK without a bot tile on supported setups.
Why Choose Recall.ai
- A good fit when you want raw meeting data and will build your own summaries and agent logic on top.
- Wide platform coverage and live streams help teams ship conversation AI products.
3. Meeting BaaS

Meeting BaaS is a developer API for meeting data across Zoom, Google Meet, and Microsoft Teams. It is hosted and ready to use, with the option to run it on your own servers when you need more control.
One Request, Recordings, Transcripts, And Speaking Bots
Send a meeting link and a bot name in one simple request, and the bot joins Zoom, Google Meet, or Microsoft Teams as a named participant. It records the call, can listen, speak, and use chat, and your system gets a webhook when the data is ready.
Transcription is built in, and you can pick your own provider, such as Deepgram or AssemblyAI, with AI summaries and translation as extra options. Moreover, live audio can stream both ways, so a speaking bot can hear the room and talk back. And when data needs to stay with you, you can keep files in your own cloud storage or run everything on your own servers.
Key Features
- One bot style for three platforms: The same meeting URL and webhook response work for Zoom, Google Meet, and Microsoft Teams.
- Recordings and participant data: Capture video and audio, the list of participants, and every chat message from the call.
- Built-in transcription: Turn on transcription with your choice of provider, including your own provider keys.
- Speakers separated in the transcript: Separate who said what, with timestamps for each speaker.
- AI summaries and translation: Create AI summaries and translate transcripts through transcription options.
- Two-way audio for speaking bots: Stream live audio in and out so your agent can take part, not only take notes.
- Calendar scheduling and data control: Connect calendars and schedule bots for upcoming meetings, then keep files in storage you control or on your own servers.
Why Choose Meeting BaaS
- A balanced path: hosted bots with transcription and summaries today, plus your own storage or your own servers for stricter data rules.
- Public APIs and SDKs help teams plug bots into their products quickly. There is also a connector that lets AI agents use Meeting BaaS as a tool.
4. Attendee

And finally, Attendee is an open-source API for building meeting bots on Zoom, Google Meet, and Teams. It hides the hard parts of each platform behind a simple API, and it is designed so you can run it on your own servers.
Open-Source Bots With Webpage Voice Agents
In Attendee, a bot joins Zoom, Google Meet, or Microsoft Teams to record and transcribe, and it can also speak, show a camera image, and use chat. For voice AI, you simply give it a link to your voice agent webpage. Attendee then streams that page into the call and feeds the meeting audio back as its microphone.
Therefore, anything that already works in a browser, even an avatar, can join a meeting. Attendee also streams live audio both ways, with paths for the Deepgram Voice Agent API and the OpenAI Realtime API And transcripts can come in real time, with support for multiple languages and speaker identification.
Key Features
- Open source and self-hostable: Run Attendee on your own servers, using a simple API for Zoom, Meet, and Teams.
- Webpage voice agents: Drop in a public webpage link, and Attendee streams its audio and video into the call while feeding meeting audio back as the mic.
- Two-way live audio: Stream audio both ways when you prefer your own audio setup over a webpage.
- Speech, avatars, and chat: Speak into the room, show a camera image, and send or record chat messages.
- Flexible transcription: Choose third-party providers or closed captions, with speaker identification and language options.
- Calendar scheduling: Auto-schedule bots from Google or Microsoft calendar events so you do not miss calls.
Why Choose Attendee
- A good fit when you want open source and bots running on your own servers.
- A helpful path for teams that already built a browser-based voice agent and need it inside Zoom, Meet, or Teams.
What To Take Away
Voice AI meeting bots in 2026 are more than silent recorders. The platforms above all join major video meetings through an API. They capture transcripts, and each of them can speak back.
- Telnyx is a good match when you want a managed bot that listens, talks, chats, and summarizes under one API key, with an optional AI Assistant in the room.
- Recall.ai fits teams that need deep meeting data and Output Media for custom agents.
- Meeting BaaS pairs hosted bots with built-in transcription options and a clear speaking-bot stream.
- Attendee is an open-source path for self-hosted bots and webpage voice agents.
So, pick based on what you need most: a full voice AI participant with summaries, raw meeting data, transcription with self-host flexibility, or open-source control.
Then start with a single meeting URL and let the bot join.
