PhoneTag’s Automated Voice-to-Text Service Is Only 86 Percent Accurate, But That’s Better Than Google Voice
Computer voice-to-text technology has come a long way, and every time it gets better, new applications open up. It is still not 100 percent accurate. Hell, it's not even 90 percent accurate. But it is accurate enough for automated voicemail transcription services to become increasingly available and good enough not to have to listen through 15 voicemails to get the gist of what they are about. Of course, voicemails are often translated incorrectly, sometimes to comic effect . In a study comparing the accuracy of four different voice-to-text technologies (Google Voice, Preview in Microsoft Exchange, Ditech's PhoneTag, and Yap ) the one which came out on top was PhoneTag, which is now part of Ditech Networks . PhoneTag showed an 86 percent accuracy rate in translating 500 spoken messages into text. Google Voice was only able to achieve an 82 percent accuracy in its voice-to-text translations. The study only evaluated purely automated voice-to-text systems. Here's how all four fared:
