Data Capture

Frequently Asked Questions

What is audio transcription?

Audio Transcription is the concept of listening to an audio file (usually via headphones) and creating computer readable information from it.

One common application involves the transcription of a recording made during a meeting or interview so that comments can be reviewed easier than listening to the entire recording again. Another application is to transcribe spoken information left on automated answering machines. Typically, these are responses to charity appeals or entries to competitions on TV. The caller leaves their contact details and perhaps credit card information which is transcribed into a structured data record for further processing.

What types of transcription do you do?

We transcribe meetings, interviews, focus groups, court proceedings and many other types of recordings. In addition, we specialise in transcribing ‘audio data’ which involves transcribing personal details such as name, address, credit card details etc that callers have left on an automated telephone answering system. Each element is transcribed into a different field within a structured data record.

There is a case study of how Ndata managed the credit card donations toward the Asian tsunami appeal here.

How long does it take to transcribe an audio recording?

If the recording is of spoken sentences (such as two or more people talking) then the time varies depending upon several factors: was the recording digitally made? how many speakers? are there any echoes in the room etc? With good quality recordings the audio may need to be played 3 times to ensure the quality of the final word document. In the case of recordings where the information needs to be transcribed into a structured data record, there is often less need to play the audio several times because the range of possible responses in each element is limited and the transcriber is aware in advance of the possible valid answers.

Can't this be done automatically these days by voice recognition?

It’s possible for voice recognition to identify individual words when there is a narrow range of valid responses (for example a spoken number between ‘one’ and ‘ten’). However, considering the range of dialects, regional accents and even which part of the world the speaker comes from, its impossible to rely on anything more.

How do you ensure quality?

Firstly, we process the source audio file into a standardised format which our bespoke software has been built around which allows us to use advanced features. For example, it allows us the operative to move back 1 second simply by hitting F1 or 2 seconds by hitting F2 etc if a spoken word is difficult to understand. These sort of functions make a significant reduction in time and improvement in quality. After the transcription has been completed the same specialist will spell check their own work and then pass the file to our QA staff. At this point the entire word document is proof read to ensure that it is of the quality that you expect.
 

Do you sub-contract transcription?

We don’t outsource transcription to unknown typists either in UK or abroad. Ndata’s focus is always on quality and accountability and to this end we only transcribe using our own dedicated staff. All of our staff are DBS (formerly CRB) checked and cleared and have been working with us for many years. Most transcription done abroad is of a poor quality since accurate transcription requires that the operative has an excellent cultural understanding of the words used on the recording and this is not possible using foreign labour.

What recording formats do you accept?

MP3, WAV, MOV, AVI, MP4, AIFF, and hundreds more. We accept audio and video recordings in MP3, MP4, WMV, AIF, M4A, MOV, AVI, VOB, AMR, WMA, OGG, and WAV. We also accept tapes or CD’s. If you have a file in a format other than those listed here, please contact us. We also accept links to streaming video and audio files available on the web.

How do I get audio recordings to you?

Simply contact us and advise that you wish to give us a recording to transcribe. If you have a digital recording the procedure is extremely simple. We can set you up immediately on our secure server with your own private area, simply connect and drag and drop the recording into the folder we have allocated you.

Accuracy is at the centre of everything we do

Accuracy is at the centre of everything we do

Data can be an organisation’s most valuable asset but what if it’s accuracy is flawed? That asset could be of little value or worse still deemed useless.

That’s why getting its capture right in the first place is fundamental.
