Interview transcription you can quote with confidence
An hour of interview is four to six hours of typing, and the quote you need is always in the part you summarized. Klang transcribes interviews with named speakers and links every sentence to the audio, so quoting, coding and verifying take minutes.
01
What interview work demands from a transcript
Interviews are not meetings. Nobody needs the decisions and to-dos; you need what was actually said, by whom, exactly, and you need to defend it later: in a paper, a case file or a report.
- Verbatim accuracy, including the hesitations that carry meaning in qualitative work
- Reliable speaker separation between interviewer and respondent, also with several respondents
- A quote you can verify: click the sentence, hear the original
- Timestamps for citation and for jumping back into context
- Confidentiality: interviews contain personal data, often sensitive
02
How Klang handles interviews
Record the interview with the Klang mobile app, or upload files afterwards: audio or video, all common formats, one interview or a batch of forty.
Klang transcribes in more than 40 languages, separates and names the speakers, and keeps every sentence linked to its place in the recording. You correct directly in the transcript with the audio one click away, then export in your usual format or keep working inside Klang.
03
Analysis across the whole study
The transcript is where interview work usually stalls: twenty interviews, four hundred pages, and the themes hiding across them. In Klang you gather the interviews you choose and analyze them together: ask which respondents mentioned a theme, compare answers across interviews, or generate a structured report.
Only the sources you explicitly add are analyzed, and every claim in the output cites the interview and the exact moment. You stay in control of what goes in, and you can verify everything that comes out.
04
Confidentiality is not a feature, it is the baseline
Research and investigative interviews are as sensitive as data gets. Klang processes everything in Europe, offers a data processing agreement, never uses your recordings to train AI, and is ISO 27001:2022 certified.
Universities and public agencies use Klang for exactly this kind of material, and for organizations whose recordings cannot leave their own infrastructure, Klang runs on-premise, fully offline if required. Consent from participants remains, as always, your responsibility.

Frequently asked questions
How long does it take to transcribe an interview?
By hand, four to six hours per hour of audio. With Klang, an hour-long interview is transcribed in minutes, with speakers separated, and your time goes into reviewing and correcting rather than typing.
Is automatic transcription accurate enough for research?
As a working transcript, yes, and correction is fast because every sentence links to the audio. For strict verbatim standards, review the passages you cite; clicking a quote plays the original, so verification takes seconds per quote.
Can it separate the interviewer from the respondent?
Yes, automatically, and you can name the speakers. It works with several respondents, and also for recordings made in a room rather than in a call.
Can I analyze many interviews together?
Yes. Gather the interviews of a study and ask questions across them, compare answers or generate a structured report. Only the sources you add are used, and every claim cites the interview and the exact moment.
Is it GDPR compliant for sensitive interviews?
Klang processes all data in Europe, offers a data processing agreement, never uses your recordings to train AI and is ISO 27001:2022 certified. For material that cannot leave your infrastructure, an on-premise installation is available. Participant consent remains your responsibility.
