Free Otter.ai Alternative for Transcribing Files

Otter.ai is a meeting assistant that joins your calls and takes notes. If what you really need is to transcribe a recording you already have, free and without an account, Speechma’s Speech to Text (open above) does it in 43 languages. Speechma does not join live meetings.

In short: For transcribing audio files, Speechma is a free Otter.ai alternative: upload a recording from 5 seconds to 1 hour and get plain text or timestamps per sentence, plus an SRT subtitle file, in 43 languages with no account. Otter.ai is built for live meetings: its free Basic plan includes 300 minutes a month, 30 minutes per conversation and 3 lifetime file imports, in six languages.

Otter.ai and Speechma solve different problems

Otter.ai is a meeting tool. It joins Zoom, Microsoft Teams and Google Meet, writes notes, and shares them with your team. If you want an assistant in every call, that is what Otter is designed for, and Speechma is not a replacement. Speechma has no meeting bot and no live transcription.

Speechma is for files. You recorded an interview on your phone, a lecture, a podcast episode or a Zoom call you saved, and you want the words. Otter’s free plan allows only 3 file imports per user in total, so people who mostly transcribe files often look for another option. Speechma’s speech to text has no account and handles each file up to 1 hour long.

How to transcribe a recording on Speechma

  1. Upload the audioAny recording from 5 seconds to 1 hour. For a longer file, cut it into hour-long parts first.
  2. Pick the languageChoose the spoken language from the 43 supported, for example English, Spanish or Hindi.
  3. Choose the outputPlain text for notes and articles, or timestamps per sentence for editing and captions.
  4. DownloadCopy the text, or download an SRT subtitle file when timestamps are on, ready for YouTube, Premiere or CapCut.

What people transcribe with Speechma

Interviews

Journalists and researchers turn phone recordings into quotable text. See interview transcription.

Lectures

Students transcribe recorded classes to study from. See lecture transcription.

Podcasts

Create show notes, blog posts and captions. See podcast transcription.

Saved meetings

Download your Zoom or Teams recording, then transcribe the file. See meeting transcription.

Video captions

Turn on timestamps and download an SRT for your video.

Non-English audio

43 languages, so a Spanish voice memo or a German webinar works too.

When Otter.ai is the better choice

If your team spends the day in calls and wants notes written automatically and shared in one place, Otter.ai is built for that and Speechma is not. Live transcription, a bot that joins meetings, and team workspaces are all Otter strengths. Business plans also offer unlimited transcription and meetings up to 4 hours.

Speechma is the better fit when you have files, not meetings: a podcast, a lecture, an interview, a voice memo. It is also useful for audio in languages Otter does not list, such as Hindi, Portuguese, Korean or Arabic.

A good workflow for many people: record the meeting with your usual app, then transcribe the saved file on Speechma when you actually need the text.

Tips for accurate transcripts

  • Record close to the mic. A phone on the table a foot away beats one across the room.
  • Reduce overlap. People talking at the same time is the hardest thing for any transcription tool.
  • Pick the right language. Choosing the spoken language helps with names and accents.
  • Check proper nouns. Search the transcript for names and product terms and fix them once.
  • Get consent. Some US states require everyone’s permission before a call is recorded.
