Among the topics I cover in this series of Rip Off Britain: Live on BBC1 is speech recognition. In Tuesday’s show I went to Liverpool to investigate how viewers are talking to their tech to help make their everyday lives easier.

According to researchers at Stanford University we can talk three times faster – and with 20% more accuracy – than we can type or swipe on a mobile phone.

Proof that it’s good to talk, right?

It was no surprise, however, to find that many I spoke with were initially sceptical about the effectiveness of speech recognition. But I had a hunch that their lack of confidence was misplaced, with judgements on poor comprehension based on older generations of the technology.

Our day of filming in and around Liverpool proved my point: I found that Apple’s intelligent personal assistant Siri was better than even I was at comprehending commands, irrespective of accent or background noise.

Speech recognition technology – and Siri is far from the only or even the best example at present – has now reached a level of useful maturity. What is needed next to help more to benefit from it is further accessibility and behavioural change.

In the main Rip Off Britain series in September I also took a look at how voice biometrics are being used by major service providers as an authentication factor to make logins to our online accounts safer, simpler and more secure.
