Why AskSia

What makes AskSia a strong tool to transcribe AMR files.

Most transcribers reject AMR or insist on conversion first. AskSia accepts .amr and .3ga directly and is tuned for the compressed phone-grade audio AMR is built for.

Built for AMR audio

Compressed and phone-grade audio is harder than studio recordings. AskSia stays accurate on AMR thanks to context-aware processing for names, numbers, and conversational speech, with 95% or higher accuracy on clear AMR.

95%+ on clear AMR

No conversion, drag and drop

Drop the .amr or .3ga in as it is, no codec changes, no re-encoding. AskSia handles AMR-NB and AMR-WB out of the box, plus 3GP audio containers (.3ga) commonly used by Samsung and other Android recorders.

AMR-NB, AMR-WB, 3GA

Speaker labels for any conversation

AskSia identifies up to 10 distinct speakers in a single AMR recording, color-codes their turns, and timestamps each one. Useful for voicemails left by multiple people, conference calls, and family or group recordings.

Up to 10 speakers, renameable

A useful transcript, not just text

Once an AMR is transcribed, the AI assistant Sia can pull out callback information, action items, key dates, summaries, or quick notes. The transcript becomes structured information you can act on instead of an audio playback you have to listen to twice.

Use Cases

What people transcribe AMR files for.

🏛

Android voice recorder notes

Many Android voice recorder apps save voice memos as AMR or 3GA. Drop them into AskSia to turn quick spoken thoughts into structured text in seconds, useful for writers, founders, students, and field workers.

Android voice memos
💻

Voicemail messages

Carrier visual voicemail systems and many PBX systems save AMR recordings. Upload an AMR voicemail to read the message instead of replaying it, with the caller, reason, and callback summarized by the AI assistant.

Older feature-phone recordings

Recordings from older Nokia, Samsung, and Sony Ericsson feature phones often come as AMR. AskSia turns these legacy files into searchable text, useful for digitizing personal archives or preserving family history.

Field interviews and qualitative research

Some field-research devices and apps default to AMR for compact storage. AskSia transcribes them with speaker labels and timestamps, ready to quote, code in NVivo or Atlas.ti, or analyze.

Language learning archives

Old language-learning programs and dictation devices often saved practice audio as AMR. AskSia transcribes the original audio and can translate it side by side, useful for learners returning to materials they already own.

Customer service and support archives

Some call-center systems archive interactions in AMR for storage efficiency. AskSia transcribes those recordings (with appropriate consent and compliance) for search, training, and quality review.

FAQ

Common questions about transcribing AMR files.

How do I transcribe an AMR file to text?
Drag the AMR file into AskSia, or click upload and select the file from your computer or phone. AskSia processes the audio with AI speech recognition tuned for compressed AMR audio and returns a timestamped transcript with up to 10 speakers labeled automatically, usually in seconds. The transcript can be translated into more than 40 languages and exported as TXT, DOCX, or SRT subtitles. The free plan covers AMR files up to 30 minutes.
What is an AMR file?
AMR (Adaptive Multi-Rate) is an audio compression format optimized for speech, originally developed for mobile phone calls and recordings. AMR files are common on Android voice recorders, older feature phones, voicemail systems, and legacy phone archives. The format is highly compressed and tuned for spoken audio rather than music, which is why standard audio players sometimes struggle with AMR. AskSia handles AMR-NB and AMR-WB directly without conversion.
Do I need to convert AMR to MP3 or WAV first?
No. AskSia transcribes AMR files directly, including .amr and .3ga extensions, in both AMR-NB and AMR-WB encoding. There is no need to convert to MP3, M4A, or WAV first. Skipping the conversion step preserves the original audio without an extra round of compression.
How accurate is AskSia at transcribing AMR files?
On clear AMR audio, AskSia reaches 95 percent or higher accuracy. AMR is a phone-grade compressed format, which is harder than studio audio. AskSia stays usable in those conditions thanks to context-aware processing for names, numbers, and conversational speech. Very noisy or muffled recordings may need a quick proofread.
Can AskSia transcribe AMR files in other languages?
Yes. AskSia transcribes AMR audio in more than 40 languages and detects the source language automatically. You can also translate the transcript at the same time, so an AMR voice memo or voicemail in Spanish, Mandarin, French, or Arabic can be read in English alongside the original. Supported languages include English, Spanish, Mandarin, French, German, Portuguese, Japanese, Korean, Arabic, and Hindi.
Where do AMR files usually come from?
AMR files most often come from Android voice recorder apps, older feature phones, voicemail systems (carrier visual voicemail and PBX systems), and legacy phone archives. Some Bluetooth headsets, dictation devices, and language-learning recorders also output AMR. AskSia handles all of these sources without conversion.
Is it free to transcribe AMR files with AskSia?
Yes. AskSia is free to start. The free plan covers AMR files up to 30 minutes each. AskSia Pro and AskSia Super remove the duration limit and unlock features like Google Docs export, higher-accuracy tiers, and the full AI study companion.
