MacSpeech on Thursday announced MacSpeech Scribe, a transcription application for the Mac that turns your voice recording into written text. It costs $149, and MacSpeech Dictate users can get it for $99.

MacSpeech Scribe creates a “speech profile” from an initial recorded sample of your voice, and can transcribe spoken English with 99 percent accuracy, according to the developer. It will also recognize spoken punctuation. Audio file formats supported include .wav, .aif, .m4v, .mp4 or .m4a.

System requirements call for Mac OS X 10.6 or later.

In related news, MacSpeech has also introduced Scribe Medical and Scribe Legal, two new add-ons for its Dictate Medical and Dictate Legal applications. Either add-on costs $99.

Each add-on both work similarly to the standalone Scribe product, though they feature support for specific vocabularies used in the medical and legal professions, respectively.

Scribe Medical supports more than 54 medical and dental disciplines, while Scribe Legal recognizes more than 30,000 legal-specific words and terms.

MacSpeech is also using Macworld Expo to demonstrate its “via Dictate” iPhone extension app, which lets the iPhone be used as a remote extension of MacSpeech Dictate when the software is running on a Macintosh. MacSpeech doesn’t plan to charge for the app, though it will require a Mac running MacSpeech Dictate in order to work.
