IBM ViaVoice is a range of language-specific continuous speech recognition software products offered by IBM. The current version is designed primarily for use in embedded devices. The latest stable version of IBM Via Voice was 9.0 and was able to transfer text directly into Word.

Users were able to improve decoding accuracy, by reading prepared texts of a few hundred sentences. The recorded data was used to tune the acoustic model to that specific user. In addition, user specific text files could be parsed to tune the language model. Correction of mis-recognised words was also used to improve subsequent decode accuracy.


Individual language editions may have different features, specifications, technical support, and microphone support. Some of the products or editions available are:

  • Advanced Edition,
  • Standard Edition,
  • Personal Edition,
  • ViaVoice for Mac OS X Edition,
  • Pro USB Edition,
  • Simply Dictation for Mac.


Prior to the development of ViaVoice, IBM developed a product named VoiceType. In 1997, ViaVoice was first introduced to the general public. Two years later, in 1999, IBM released a free of charge version of ViaVoice.

In 2003, IBM awarded ScanSoft, which owned the competitive product Dragon NaturallySpeaking, exclusive global distribution rights to ViaVoice Desktop products for Windows and Mac OS X. Two years later, Nuance merged with ScanSoft.[1]
