Transcribing your audio…

What makes phone call recordings hard

Phone audio is deliberately narrow. Traditional telephony carries roughly 300 Hz to 3.4 kHz, discarding the frequencies that distinguish similar consonants — which is why s and f are so easily confused on a call and why phone recordings transcribe measurably worse than anything recorded in a room.

A workflow that holds up

1

Record from the call platform rather than by holding a second phone near the speaker.

2

Upload the recording directly; call platforms typically export MP3 or WAV.

3

Expect to correct names and numbers, which are the most commonly damaged elements.

4

Keep the timestamped version if the call may become a reference later.

Things worth knowing first

  • → VoIP calls on a wideband codec transcribe noticeably better than traditional phone lines.
  • → Confirm important numbers verbally on the call itself — it gives the transcript a second chance at them.
  • → Check the recording consent rules in the jurisdictions of everyone on the call.

What you get back

Every job returns both versions. Take whichever fits the job.

Questions about phone call transcription

Telephony throws away the high frequencies that separate similar consonants. That loss happens before transcription and cannot be recovered.
Yes. Wideband codecs used by modern conferencing tools carry far more of the speech signal than a traditional phone line.
It depends entirely on jurisdiction, and some require all parties to consent. Check the rules that apply to everyone on the call.
