New Machine Caption Options Look Interesting

By: Todd Stabley

We wrote in April of last year about the impact of new AI and machine learning advances in the video world, and specifically around captioning. A little less than a year later, we’re starting to see the first packaged services being offered that leverage these technologies and make them available to end users. We’ve recently evaluated a couple options that merit a look:

Syncwords

Syncwords offers machine transcriptions/ captions for $0.60/per minute, and $1.35/ minute for human corrected transcriptions. We tested this service recently and the quality was impressive. Only a handful of words needed adjustment on the 5 minute test file we used, and none of them seemed likely to significantly interfere with comprehension. The recording quality of our test file was fairly high (low noise, words clearly audible, enunciated clearly).

Turnaround time for machine transcriptions is about 1/3 of the media run time on average. For human corrected transcriptions, the advertised turnaround time is 3-4 business days, but the company says the average is less than 2 days. Rush human transcription option is $1.95 with a guaranteed turnaround of 2 business days and, according to the company, average delivery within a day.

Syncwords also notes edu and quantity discounts are available for all of these services, so please inquire with them if interested.

Sonix.ai

Sonix is a subscription-based service with three tiers: single-User ($11.25 per month and $6.00 per recorded hour/ $0.10/minute), Multi-User ($16.50 per user/month and $5.00 per recorded hour) , and Enterprise ($49.50 per user/month, pricing available upon request).  You can find information about the differences among the tiers here: https://sonix.ai/pricing

The videos in the folder below show the results of our testing of these two services together with the built in speech-to-text engine currently utilized by Panopto. To be fair, the service currently integrated with Panopto is free with our Panopto license, and for Panopto to license the more current technology would likely increase their and our costs. We do wonder, however, whether it is simply a matter of time before the currently state-of-the art services such as featured here become more of a commodity:
