Accurate AI transcripts from a room

Summary

A room transcript is only as good as the audio the AI hears. Get that right first: one set of live mics and speakers in the room, mics close to every seat, and a room that isn't too echoey or noisy. Then choose how to capture it. If you want the transcript to name who in the room said what, Microsoft Teams Rooms speaker recognition is the option in our sources that does it automatically, from enrolled voice profiles. Get everyone's consent and check local recording laws before you record.

None of Zoom, Microsoft or Google publishes a word error rate for its transcripts on the pages we opened, so this page gives no accuracy numbers for them. We found no named reviews that test room transcripts, so it uses maker pages only. CrimsonBot has not tested any of these.

Before recording a phone call, tell everyone on it and ask for their consent. Some states require consent from everyone on the call, and an interstate call can bring in the stricter state's law (RCFP guide: https://www.rcfp.org/reporters-recording-guide/). This is general information, not legal advice.

Step 1: Fix the room audio first

• One device with live audio per room. Several computers with active audio in one room is one of Zoom's three common echo causes. Muting isn't enough: "you mute the mic, but the speaker is still on" (Zoom).
• Mics near every seat. Microsoft's design guidance for a rectangular table: "Place at least two microphones on the conference table so that no participants are more than a few feet from one," with coverage overlapping (Microsoft Learn). Logitech says to check mic pickup range covers the whole room (Logitech room design guide).
• A quiet, not-too-live room. Zoom's rule of thumb is reverb time (RT60) of no more than half a second, and a noise floor ideally no louder than 40 dB SPL A-weighted (Zoom).

Step 2: Choose how to capture the room

Microsoft Teams Rooms: who said what

Who it fits: Microsoft 365 offices that need the transcript to name each speaker in the room.

With an Intelligent Speaker, Microsoft says the transcript can "distinguish between different speakers in the room" and "attribute them to the correct person." Microsoft says certified intelligent speakers use multiple mics to "maximize accuracy in recognition and transcription," but gives no number. The feature now works on all Teams Rooms devices, though "the quality may not match that of an intelligent speaker certified device." Without speaker recognition, in-room speech is attributed to the room, for example "Conference Room 1" (Microsoft Learn).

Requirements, from the same page:

• Teams Rooms: a Teams Rooms Pro license. BYOD rooms: the room host needs Teams Premium or Copilot.
• People must enroll a voice profile and be invited to the scheduled meeting.
• Transcription must be on, and the organizer's mailbox must be in Exchange Online (not on-premises Exchange or a third-party calendar such as Google Calendar).
• For the best transcript, Microsoft suggests limiting in-person attendees to 10, and recommends 10 Mbps room upload speed.

Teams Rooms Pro is $40.00 per room per month, paid yearly (Microsoft). Teams Premium is $10.00 per user per month, paid yearly (Microsoft). Both prices checked 2026-11-12.

Zoom: Voice Recorder or Zoom Room summaries

Who it fits: Zoom offices recording in-person meetings with a phone, or in a Zoom Room.

Zoom's Voice Recorder with AI records, transcribes and summarizes in-person conversations. It needs a Pro, Pro Plus, Business, Business Plus, Education or Enterprise account and the Zoom mobile app 6.4.5 or higher, with Voice Recorder, meeting summary, automated captions and cloud recording turned on. Zoom says Voice Recorder "is upgrading to My Notes" in version 7.0.5 or later. Its own reminder: "make sure you follow all applicable laws when monitoring or recording conversations" (Zoom, Voice Recorder with AI). Zoom also lists meeting summaries for in-person meetings "with your device or Zoom Room" (Zoom AI features).

Google Meet: in-person "Take notes for me"

Who it fits: Google Workspace teams, for scheduled or impromptu in-person meetings, with no meeting room needed.

On Android, open the Meet app, tap Take notes > Start taking notes, and "set your device nearby." If someone remote wants to join, you can switch to a normal video call. Notes are emailed and saved in the Drive of whoever turned it on. It needs an eligible Workspace edition or Google AI plan, held by the organizer. Google says a summary can be "incomplete, inaccurate, or not generated," for example on connectivity problems or meetings shorter than 15 minutes (Google Meet Help).

A separate notetaker

Who it fits: teams that already use one across platforms.

• Otter says it reaches "up-to-95% transcription accuracy" in good audio, citing PCMag testing, and adds that heavy background noise and strong accents push it lower, so "treat the 95% figure as a best case rather than a guarantee" (Otter blog, Jul 21, 2026). That is Otter's own claim, and Otter's blog does not say the test used room mics. We have not checked PCMag's test directly.
• Fireflies announced Fireflies Fly, a device that attaches to a phone and takes notes for calls and in-person conversations, with availability "expected early next year." It has no confirmed price. Fireflies' own advice: "make sure everyone knows when they're recording and follow local recording rules" (Fireflies press release, Nov 11, 2026).

For plan requirements side by side, see the guide on built-in Zoom, Teams and Meet AI vs a notetaker, on the way on the AI notetakers hub. For room gear costs, a cost guide, What a room costs: DIY vs installer, is on the way.

Unverified / not covered

• Official accuracy or word-error-rate figures for Zoom, Teams or Google Meet. None were published on the pages we opened.
• Any test comparing a room video bar with a meeting bot for transcript accuracy.
• Fireflies Fly price and ship date.
• PCMag's original test (cited only via Otter).
