Free online AMR to TXT converter

Source format: AMR

AMR usually means Adaptive Multi-Rate audio, a compressed speech-focused audio format designed for voice recordings and telephony. It is commonly used in mobile phones, VoIP systems, voicemail archives, and messaging apps where speech clarity and small file size matter more than music quality. AMR files are typically saved with the .amr extension.

Target format: TXT

TXT is a plain-text format that stores only readable characters, with no audio data. It is commonly used for transcripts, notes, captions, logs, and searchable text. Converting AMR to TXT usually means transcribing the speech in the audio into written text, because audio cannot be directly saved as plain text without speech recognition or manual transcription.

How to convert AMR to TXT

There is no direct file-format conversion from AMR to TXT. You need to extract the spoken content from the AMR file and turn it into text using speech-to-text software or manual transcription.

1. Check the AMR file: Make sure the file plays correctly. If needed, open it in a media player that supports AMR, such as VLC.
2. Choose a transcription method:
   • Manual transcription for short recordings or when accuracy is critical.
   • Speech recognition software for faster results on longer recordings.
3. Transcribe the audio:
   • If your speech-to-text tool accepts AMR directly, upload the .amr file and export the transcript as .txt.
   • If the tool does not support AMR, first convert the audio to a more widely supported format such as .wav or .mp3 using desktop software like FFmpeg, then run transcription.
4. Review and clean up the transcript: Correct names, punctuation, and recognition errors, then save the final result as .txt.
5. Optional online conversion: You can convert small files for audio-to-text transcription on 101convert.com for free, without installing any software.

Example FFmpeg command to convert AMR to WAV before transcription: ffmpeg -i input.amr output.wav

Notes on quality and limitations

Accuracy depends on audio quality, background noise, speaker accents, overlapping speech, and the speech recognition engine used. AMR is optimized for voice and often has a lower bandwidth than studio audio, so transcripts may contain more errors than those made from high-quality recordings. If the recording is noisy or contains multiple speakers, manual correction is usually necessary.

Also, TXT cannot preserve audio, timestamps, speaker labels, or formatting unless the transcription tool adds them before saving. If you need timestamps or speaker separation, consider exporting to a richer text format first and then saving a plain-text copy if needed.
