(Note for Google the latest result is from latest-long model, other Google results are from video enhanced.) We now have done the same benchmark 4 times so we can draw charts showing how each of the recognizers has improved over the last 1 year and 9 months.
Note, the numbers do not add to 63 because there were a few files where two recognizers had identical results (to 2 digits behind comma).
Google Video Enhanced wins a participation trophy by being best on 1 file, which was a very easy "The Art of War by Sun Tzu Full" Librivox Audiobook - WER of 1.79%. Voicegain was close behind Amazon by being best on 12 audio files. Amazon was best on 15 files (note that in the October 2021 benchmark Amazon was best on 29 files). Microsoft was best on 35 out of the 63 files. Let's look at the number of files on which each recognizer was the best one. Google latest-long, Voicegain, and Amazon are now very close together, while Microsoft is better by about 1 %. The chart also reports the average and median Word Error Rate (WER)Īll of the recognizers have improved (Google Video Enhanced model stayed much the same but Google now has a new recognizer that is better). You can see boxplots with the results above. It was a bad quality phone interview ( Byron Smith Interview 111416 - YouTube). This time only one file was that difficult. We have repeated the test using similar methodology as before: used 44 files from the Jason Kincaid data set and 20 files published by rev.ai and removed all files where none of the recognizers could achieve a Word Error Rate (WER) lower than 25%. We have decided to no longer report on Google Standard and IBM Watson accuracy, which were always far behind in accuracy. Accuracy of Video Enhanced stayed pretty much unchanged. Google has released a new model "latest-long" which is quite a bit better than the previous Google's best Video Enhanced model. Microsoft and Amazon both improved, with Microsoft improving a lot on the more difficult files from the benchmark set. This resulted in a further increase in the accuracy of our model.Īs far as the other recognizers are concerned: Since then we have obtained more training data and added additional features to our training process. Back then the results were as follows (from most accurate to least): Microsoft and Amazon (close 2nd), then Voicegain and Google Enhanced, and then, far behind, IBM Watson and Google Standard.

There are no acoustic models and audio quality settings for speech engine, however, on XP machine, you may set the recognition quality vs. The more you train your computer, the better result you could get. Best accuracy requires 4-5 hours of training. Accuracy is improved by training and audio quality. In the Settings > Time & Language > Speech, you may also find these methods important. Tips to Improve the Accuracy of the Speech Engine Users can have more than one profiles for each login. You may export then import the profile to reuse the training info on different logins or computers. Once the training is complete, you do not need to train again. Add words to the speech recognition dictionaryĬomplete all the steps that is necessary. Train your computer to understand your voice. Speech-to-Text will only be available if there is audio on the timeline.īefore using the Speech-to-Text feature, the following training must be completed in order for the speech recognition to be successful. This can be found within Captions by selecting the gear icon. After installing Camtasia, the speech recognition features will be ready to use. There is no need to install the engine again.
