AskSia turns iPhone, Android, Google Voice, and VoIP phone call recordings into accurate text in minutes. Drop an M4A, MP3, or AMR file into the web app, upload from your phone, or paste a direct audio link. The transcript appears with speaker labels for caller and recipient, plus an optional translation in 40+ languages. AskSia is intended for use only on calls you are legally permitted to record. Free to start.
To transcribe a phone call to text, you save the call recording from your phone or VoIP service as an audio file and upload it to AskSia. iPhone call recordings save as M4A. Android call recorders typically save as MP3, M4A, or AMR. AskSia processes the audio with AI speech recognition tuned for phone-line quality, and returns a timestamped transcript in minutes, with speaker labels separating caller and recipient. The transcript can be translated into more than 40 languages and exported as TXT, DOCX, or SRT subtitles. The free plan covers phone call recordings up to 30 minutes, which covers most personal and customer service calls.
Phone call audio is compressed, sometimes noisy, often spoken quickly, and full of names and numbers. AskSia is built for real-world recordings, not just studio audio.
Phone call recordings are recorded at low bitrate and pass through phone networks before reaching your inbox. AskSia stays accurate on that kind of audio thanks to context-aware processing for names, numbers, and conversational speech, with 95% or higher accuracy on clear calls.
Apple call recordings (M4A), Android stock recorders, Google Voice, Skype, Zoom Phone, RingCentral, and most third-party recorder apps all produce files AskSia handles directly. One tool covers every common phone call format.
AskSia separates the two voices on a one-to-one call automatically, color-codes their turns, and timestamps each one. Conference calls with up to 10 speakers are handled the same way. Rename the speakers after the call to 'Me' and 'Customer' or any other label.
Once a phone call is transcribed, the AI assistant Sia can pull out the caller's reason for the call, key decisions, action items, and follow-ups. The transcript turns into a structured summary you can act on, share, or paste into a CRM.
On iPhone, save the recording from the Phone app's call recording feature, Voice Memos, or your call recorder app. On Android, save it from the stock Phone app, Google Voice, or a recorder app. Export the file to your phone or computer.
Drag the file into the AskSia web app, or upload it from the AskSia mobile app. AskSia detects the source language automatically and accepts M4A, MP3, AMR, WAV, OGG, and most other audio formats with no conversion.
The phone call transcript appears with speaker labels and timestamps. Ask Sia for a call summary, follow-up email draft, or list of action items, then export the result as TXT, DOCX, or send to Google Docs.
Forward the call recording to yourself from your phone, drop it into AskSia on your laptop, or upload it from the AskSia mobile app.
Drag a folder of saved phone call recordings into the AskSia web app and process them in sequence. The split-panel layout shows the transcript on one side and the AI chat on the other, useful for triaging customer calls or building a searchable archive of personal conversations.
Send the call recording to yourself from the iPhone or Android Phone app, then open AskSia and upload the audio in one tap. The transcript builds on your phone and syncs to your Web App library.
Read your personal phone call recordings instead of replaying them. Useful for important conversations with parents, partners, doctors, or family overseas, where you want a written record alongside the audio.
Save customer service call recordings (when the company tells you the call is being recorded and asks for your consent) and transcribe them for reference. Useful for confirming what was promised, scheduling follow-ups, and disputing charges.
Sales reps and account managers transcribe their own follow-up calls with prospects and customers. AskSia produces a clean transcript ready to paste into a CRM, share with the team, or summarize into a follow-up email.
Researchers and journalists conducting phone interviews (with consent) use AskSia to transcribe the conversation with speaker labels and timestamps, ready to quote, code, or analyze.
Capture client phone calls, witness statements, and consultant briefings (with appropriate consent and privilege handling) for matter notes, billing memos, and follow-up tasks.
Phone calls in Spanish, Mandarin, Arabic, French, or any of more than 40 supported languages transcribe in the original and translate at the same time, side by side.
Most transcription tools are built for meetings. AskSia is built for how students actually learn: bilingual, fast-moving, context-heavy.
