Automatic Speaker Recognition Technology

We have a close relationship with the internationally leading speech technology company, Phonexia.  This involves jointly mounting expert webinars, technology testing, and provision of training.  We use their cutting-edge automatic speaker recognition software in our casework.

Pro Bono Work

We undertake some pro bono work, usually acting where there is prima facie evidence of unfairness to a defendant or of persecution, usually at the request of charitable civil rights organisations such as Amnesty International.
