It has been over 7 months since we published our last speech recognition accuracy benchmark. 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.
Since then we have obtained more training data and added additional features to our training process. This resulted in a further increase in the accuracy of our model.
As far as the other recognizers are concerned:
We have decided to no longer report on Google Standard and IBM Watson accuracy, which were always far behind in accuracy.
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%.
This time only one file was that difficult. It was a bad quality phone interview (Byron Smith Interview 111416 - YouTube).
You can see boxplots with the results above. The chart also reports the average and median Word Error Rate (WER)
All of the recognizers have improved (Google Video Enhanced model stayed much the same but Google now has a new recognizer that is better).
Google latest-long, Voicegain, and Amazon are now very close together, while Microsoft is better by about 1 %.
Let's look at the number of files on which each recognizer was the best one.
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).
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 for Google the latest result is from latest-long model, other Google results are from video enhanced.)
You can clearly see that Voicegain and Amazon started quite bit behind Google and Microsoft but have since caught up.
Google seems to have the longest development cycles with very little improvement since Sept. 2021 till very recently. Microsoft, on the other hand, releases an improved recognizer every 6 months. Our improved releases are even more frequent than that.
As you can see the field is very close and you get different results on different files (the average and median do not paint the whole picture). As always, we invite you to review our apps, sign-up and test our accuracy with your data.

Today, we are really excited to announce the launch of Voicegain Transcribe. Transcribe is an AI based transcription assistant for recording and transcription of in-person and web meetings, live video events and webinars. Our goal is to empower users to focus on their meetings/events and leave the note taking to us.
Voicegain Transcribe is built on top of our highly accurate deep-learning-based ASR. It is powered by the same Speech-to-Text APIs that all our developer/platform customers use today. Our out-of-the-box accuracy of 89% is on par with the very best.
Currently there are 3 main ways you can use Voicegain Transcribe:
Users can use our browser sharing feature to record & transcribe audio that is playing on any tab on a Chrome or Edge browser. Any meeting platform that allows a browser based client is supported. Some prominent meeting platforms include Google Meet, BlueJeans, Webex and Zoom.
If the Users use a Windows based laptop/desktop, then this Browser sharing supports capturing audio from the client desktop app of the Meeting platform (e.g Zoom or Microsoft Teams). The Mac OS users does not support sharing of audio from a desktop app with Voicegain Transcribe.
This allows users to record and transcribe anything that is captured by the microphone on their laptop/desktop. So Users can turn on the microphone capture for an in- person meeting, lecture or event. They can also just let a web meeting or event play on their speaker and have the microphone capture what is being played on it.
Users may also upload pre-recorded audio files of their meetings, podcasts, calls and generate the transcript. We support over 40 different formats including mp3, mp4, wav, aac and ogg). Voicegain supports speaker diarization - so we can separate speakers even on a single channel audio recording.
Currently we support English and Spanish. More languages are in our roadmap - German, Portuguese, Hindi.
Voicegain Transcribe also supports the following advanced Features.
a. Projects
Users can organize their meeting recordings and audio files into different projects. A project is like a workspace or a folder.
b. Named Entities & Keywords
Users can highlight named entities (dates, currency, addresses, email id) in their meeting transcript.
c. PII Redaction
Users can also mask - in both text and audio - any personally identifiable information.
We are adding close integration with the Zoom meeting platform. With this, we can capture the actual speaker labels directly from Zoom. This will address errors related to diarization.
We are also adding a Chrome extension that will make it much easier to record and transcribe web meetings.
By signing up today, you will be signed up on our forever Free Plan - which makes you eligible for 120 mins of Meeting Transcription free every month . Once you are satisfied with our accuracy and our user experience, you can easily upgrade to Paid Plans.
If you have any questions, please email us at support.transcribe@voicegain.ai
“We selected Voicegain because they are accurate, affordable and easy to use. We deployed the entire platform in our datacenter in under 30 minutes.”
“We’re committed to improving learning for millions of students, so we selected Voicegain for its highly accurate and affordable transcription. We have been really happy with the product and its accuracy which has continually improved as they train their models.”
“Voicegain is amazing! They have a great ASR and a modern architecture. But what we really value is their prompt and timely support. We use both their MRCP ASR and STT APIs and they work great “
