Siri, Google Home and Dragon–what’s the difference?

Siri, Google Home and Dragon–what’s the difference?

By Derek Austin



The case for using speech recognition (SR) for document preparation has been lost in the hype around personal assistants like Siri and home cylinders such as Google Home. However, personal speech recognition can now be quickly deployed across desktop and, increasingly, mobile devices with highly accurate results.

The accuracy of SR designed for writing can be much greater than general systems for a couple of reasons:

  • Greater than 99% recognition accuracy is achieved because the SR system maintains a profile for each user. The profile maintains information about what the speaker sounds like as well as information about the language they use in their documents. The latter includes not only the vocabulary (words, phrases, and acronyms) used by the speaker, but also stores statistical information about which words are used together.
  • These systems learn. If recognition errors are corrected when they are made, SR can be more accurate in the future. A user’s profile can be trained on documents and emails at regular intervals to adapt to changes in matters’ terminology and new cases. For example, a new mining case might require recognition of a range of unusual place names. These words may be imported into the SR system vocabulary and shared across the organisation.

How speech recognition addresses issues

Speech recognition can streamline document creation across legal practices. Firms can improve client service and free up employees for high-value tasks that better contribute to the bottom line. By enabling legal practitioners to achieve higher documentation throughput and quality, firms can also reduce outside transcription service costs and lower the risk of compliance liabilities arising from reporting inaccuracies or missed deadlines.

Experience shows that an SR deployment will save at least a third of time that workers spend completing documentation. Calculating ROI and payback time for an SR deployment can be based on hourly staff costs multiplied by the 33% savings on the time spent writing documents.

'Dragon voice recognition software is easy, comfortable and entirely natural. It has long allowed flowing dictation to be a reality in the legal profession, and I believe it is simply critical software for Australian lawyers' says Maurice Byers Chambers senior counsel Mark Robinson.
