- they just released My Caption (I'm using it) and it lets you create or reply to messages by recording your voice - available from inside the menu-key list of options.
Like all BB speech-to-text products (including Nuance), it's server-based, so there's some turnaround time. Some of the transcription is automated, some involves humans - don't tell any military secrets.
Overall, speech to text applications get categorized in these ways:
- Speaker-dependent (has to be trained to your voice) or speaker-independent (works for everybody without training
- Limited or unlimited vocabulary
- Isolated word or connected speech
Beyond that are considerations like range of voices (old to young, gender, accents or dialects or regionalisms), latency (turnaround time from utterance to understanding), processing overhead, etc.
The voice dialer on the BB is speaker-independent limited-vocabulary and isolated-phrase in nature. MyCaption is speaker-independent, nearly unlimited vocabulary, connected speech in nature.
So your recording goes to a server, which scores itself on transcribing and may elect to involve a human in improving the transcription, then it gets sent back to your phone a couple minutes later as a message that's ready for you to approve or edit and send.
As a reporter, it's a great way for me to dictate a story into an e-mail to send to m desktop - talking is 3 times as fast as typing on a full keyboard and a lot faster compared to my thumbs on a Pearl.
It's not free, but at the moment, they are offering a very limited free trial.
