How to Transcribe a Phone Call (iPhone & Android)

How to Transcribe a Phone Call on iPhone and Android
Whether you're a journalist who needs a record of an interview, a salesperson who wants to review their calls, or just someone who missed a key detail in an important conversation — knowing how to transcribe a phone call is increasingly essential. Call recording transcription turns audio into searchable, shareable text. This guide covers what your options are on iPhone and Android, what the legal considerations are, and how to get accurate text from any recorded call.
Legal Notice: Record with Consent
Laws around recording phone calls vary significantly by country and US state. In 'two-party consent' jurisdictions (like California), all parties must agree to be recorded. Always inform the other party before recording a call. This article assumes you have proper consent.
Step 1: Record the Call
Before you can transcribe anything, you need an audio recording. Here's how to do it on each platform:
Recording on iPhone
Apple has historically been restrictive about native call recording to protect user privacy. As of iOS 18, Apple introduced a built-in call recording feature (available in some regions), but options have varied by iOS version.
iOS 18+ Native Recording
On supported devices, tap the Record button during a call. iOS will notify both parties that recording has started. The audio saves to your Notes app automatically.
Third-Party Apps (older iOS)
Apps like TapeACall, Rev Call Recorder, or Google Voice support call recording on older iOS versions. These typically route the call through a recording server.
External Microphone Method
Place your phone on speaker and record with a second device (another phone or a USB microphone into a laptop). Less convenient but works universally.
Recording on Android
Android is more flexible than iOS when it comes to call recording, though Google has been tightening restrictions in recent Android versions.
Google Phone App (Pixel)
On Pixel phones with the Google Phone app, tap 'Record' during a call. The recording saves locally and the other party is notified.
Manufacturer Apps
Samsung, Xiaomi, and other OEMs often include native call recording in their phone apps. Check your dialer settings — look for 'Record call' or 'Auto-record'.
Third-Party Apps
Cube ACR, Boldbeast Recorder, and similar apps work on many Android versions, though newer Android 14+ versions have restricted microphone access during calls.
Step 2: Locate and Export Your Recording
After the call, your recording will be in one of these places depending on what method you used:
- iOS 18 native: Saved in the Notes app, accessible from the call history
- TapeACall/similar: Saved within the app, with options to share or email
- Google Phone app (Android): Saved to internal storage under 'Recordings'
- Cube ACR/similar: App's own folder, usually /storage/emulated/0/CallRecordings
- External recording: Wherever you saved the audio on your second device
Export the audio file — typically as an MP3 or M4A — to your phone's files or directly to cloud storage. You'll need to access this file from a browser to upload it to a transcription service.
Step 3: Upload to QuillAI and Get Your Transcript
Open quillhub.ai in your mobile or desktop browser
QuillAI is a web platform — no app needed. Works on mobile Safari, Chrome, and any desktop browser.
Upload your call recording
Tap 'Upload file' and select your MP3 or M4A recording. QuillAI accepts all common audio formats.
Enable speaker identification
For a two-person call, turn on speaker diarization. QuillAI will label the transcript as Speaker 1 and Speaker 2, making it easy to see who said what.
Select language
Choose the language the call was conducted in. With 95+ languages supported, calls in Spanish, Mandarin, French, Russian, and dozens of other languages transcribe accurately.
Review and use the transcript
Your call transcript appears with timestamps and speaker labels. Search for specific topics, copy sections, or export the full text.
Use Key Points Extraction
For long sales calls or interviews, QuillAI's key points feature extracts the most important moments automatically. Instead of reading a 40-minute transcript, you get the critical action items and decisions in a bulleted list.
Audio Quality Tips for Better Transcription
Call audio quality directly affects transcription accuracy. Phone calls use compressed audio codecs that can introduce artifacts, and poor signal quality compounds the problem. Here's how to maximize accuracy:
- Use a wired earpiece rather than Bluetooth for better audio clarity when recording externally
- Avoid areas with heavy background noise — a quiet room significantly improves recognition
- Speak at a normal pace; rushing creates more transcription errors
- If using the speaker method, keep both devices close but avoid audio feedback
- VoIP calls (WhatsApp, Zoom, Teams) typically record at higher quality than traditional phone lines
Use Cases: Why People Transcribe Phone Calls
Journalism & Research
Verbatim quotes from sources are non-negotiable in journalism. A transcript with timestamps is also a legal record of what was said.
Sales & Business
Sales teams review calls to improve pitches, identify objections, and coach reps. Transcripts are faster to review than re-listening.
Legal & Compliance
Lawyers and compliance teams need accurate records of client conversations. Audio plus transcript provides both a reference and proof.
Healthcare
Doctors transcribing patient consultations (with consent) create accurate medical records faster than manual note-taking.
Education & Research
Academic researchers conducting interviews transcribe calls for qualitative analysis, coding, and citation.
What About Live Call Transcription?
Some users want transcription happening in real-time during the call — not just after. For this, tools like Google's Live Transcribe (Android) or Otter.ai's live mode work well, though they require constant data connectivity and have privacy implications.
For most use cases, batch transcription after the call (using QuillAI) is more practical. You get better accuracy, the ability to review the full context, and you don't have to worry about internet interruptions during the call itself. For a full comparison, see our article on Real-Time vs. Batch Transcription.
