How Long Does It Take to Transcribe an Interview

Posted on 13 March 2026

If you’re conducting interviews as part of a dissertation, master’s project, or PhD research, one of the first practical questions that often arises is: How long does it take to transcribe an interview?

Many researchers initially plan to transcribe recordings themselves, but quickly realise that interview transcription is far more time-consuming than expected.

Understanding how long transcription takes can help you plan your research schedule more realistically.

How Long Does It Actually Take to Transcribe an Interview?

For most recordings, the general rule of thumb is:

1 hour of recorded audio = 4–6 hours of transcription time

This can vary depending on several factors, including:

• number of speakers

• audio quality

• background noise

• accents or specialist terminology

• whether detailed verbatim transcription is required

For example, if your research project includes 10 one-hour interviews, transcription could take anywhere from 40 to 60 hours to complete. This is why many researchers begin looking for professional interview transcription services, particularly when working with multiple recordings.

Why Interview Transcription Takes So Long

Listening to an interview is very different from transcribing it.

Transcription requires repeatedly pausing, rewinding and checking the audio to ensure accuracy.

Researchers also often need to:

• identify speakers

• ensure quotes are captured correctly

• format transcripts clearly for analysis

These steps can significantly increase the time required.

Planning Transcription Into Your Research Timeline

When planning a qualitative research project, it’s important to account for the time required to process interview recordings.

Many postgraduate students underestimate how much time transcription can take, especially when deadlines for dissertations or theses are approaching.

Some researchers therefore choose to outsource transcription so they can focus on analysing their data rather than typing recordings.

Frequently asked questions

How long does it take to transcribe a one-hour interview?
For most recordings, one hour of audio takes between four and six hours to transcribe.

Can transcription be included in research funding?
In many cases universities allow transcription to be included as a research expense. Students should check with their supervisor or research office.

Do researchers usually transcribe interviews themselves?
Some do, but many outsource transcription to save time when working with multiple interviews.
