Transcription

Transcription is the process of writing down what is said in an audio recording. It seems like a simple secretarial skill, whose main requirement is an ability to spell.

That is until you try it.

When you do, you find that ‘writing down’ is not the main issue. Before you get there you have the ‘what is said’ part. Even in a clear recording, that can be surprisingly difficult.

Getting the overall meaning of the conversation is easy, but transcription requires rendering each individual word and phrase. Even in clear speech, that is far harder, taking an amazing amount of checking and re-checking. And the chance of missing errors is very high.

It’s a bit like proof-reading, but worse

Ever read a book and discovered a typo? Ever thought about how many times that page has been checked and double checked and triple checked by how many people? Mistakes are easy to miss in print, and far more so in speech.

So have respect for people who work as transcriptionists!

Transcribing indistinct audio is way harder

When we start dealing with indistinct recordings, things get far harder. It takes many many hours of careful, patient listening, checking and re-checking to get even a basic transcript.

And then comes the really important issue – how can you (or anyone) know your transcript is right?

This is where the law makes its big mistake, by developing its process on the basis common knowledge.

Common knowledge suggests that to check a transcript, you follow the written version against the audio – and note down any mistakes.

Seems simple – until you try it

Indistinct audio goes past your ears very fast – much faster than you can read a transcript (especially the kind of transcript typically produced by police). And covert recordings are often very lengthy, hours or even days of material.

Following the written version means constant rewinding, trying to find your place. It’s not just tedious. Poor quality audio is very unpleasant to listen to. It is like listening to an off-station radio, till your ears are assaulted by sudden loud clicks, whines and whistles.

Hardly surprising if some lawyers are willing to outsource this task to the jury, right?

But there is a worse problem. Even if lawyers take on the responsibility of checking their opponents’ transcripts – there is still the huge issue of priming.

The demonstrations on the main part of this site show how a transcript can influence perception without you realising it.

And once you feel you have heard words ‘with your own ears’, it is remarkably difficult to un-hear those words, even when you know intellectually that they might be wrong.

I’ve had more than one barrister dispute my evidence that a transcript is inaccurate – when my evidence favours their client! That’s how compelling the effect of a transcript can be.

So what’s the solution?

Finding a solution is a matter for discussion in individual scenarios. But even once it is found, understanding and implementing it requires unlearning by law and law enforcement of ideas which, though still unfortunately accepted as part of ‘common knowledge’, have been shown by phonetic science to be false.

The main part of the site gives some useful examples and experiences. This section adds a few additional topics.
