Transcription for Market Research and Call-Centre QA

Both of these are the same problem wearing different clothes: a large volume of recorded conversation, of which only a fraction is ever reviewed, because reviewing it means listening in real time.

The sampling trap

Most quality programmes review a small sample of calls, and everyone knows the sample is not representative — it is whatever the reviewer had time for.

Transcription changes what is reviewable. You cannot listen to ten thousand calls, but you can search ten thousand transcripts for the phrase that signals a mis-sold product, an angry escalation or a promise nobody was authorised to make. The sample stops being "the first twenty" and starts being "every call where this happened".

What to actually look for

Resist the urge to score everything. The useful searches are narrow:

• Commitments made on the phone — refunds, dates, prices
• Escalation language, and what preceded it
• Competitor mentions
• The specific product or feature you are currently worried about
• Calls where the agent and customer were not speaking the same language comfortably

Each of those is a text search, and each returns a set of calls worth listening to properly.

Consumer sessions

Market research sessions are focus groups with a commercial deadline. The transcript is what lets you go from impressions to counts — how many participants raised price unprompted, which phrasing came up repeatedly, what the actual words were rather than the moderator's paraphrase.

Session recordings share the focus-group difficulties: several voices, overlapping speech, and a room that was chosen for availability rather than acoustics. A moderator who names participants as they speak helps more than any equipment; the limits are covered in speaker diarization.

The language reality

This is the part imported QA frameworks get wrong here.

A Nigerian support call frequently opens in English and moves into Pidgin the moment the customer is frustrated or the agent is building rapport. That switch is often the most informative part of the call, and it is exactly the part a tool set to plain English will render as nonsense.

Set the language to match what really happens on your calls rather than what the script says. The languages page lists what is supported and where it is partial.

Quality of the recording

Call-centre audio is compressed by the telephony system before you ever get it. That ceiling is real and no tool removes it.

What you can control: record both sides, keep the original file rather than a re-encoded export, and if your platform offers a higher-quality recording option, take it. The storage costs less than the review time you lose to unusable audio.

Consent and handling

Recorded calls are personal data and often contain payment or identity details. Know where the audio goes: our privacy policy sets out what is stored and how to delete it, and recordings are never used to train any model.

For a team

Where a QA team shares one pool of hours on a single invoice, this becomes a department cost with a predictable shape. See the pricing section.

A free account includes transcription minutes each month with no card. Sign up and start with a handful of calls you have already reviewed manually — comparing the two is the fastest way to judge whether it fits.
