Accurate and consistent ASR
Overall, the Perfect Product!
Assembly has kept up with our startup's high volume of requests. We grew quickly from 0-180,000 users within 7 months and used Assembly from our very first MVP into our full scale production versions now. We have had practicaly no issues throughout this process - and if we did - support was quick to provide a solution.
In addition to all of the above, the price for the product is perfect.
The other downside is the number of customizable outputs from the API. We wanted our Speech to Text output to deliver us an SRT file that only displays one word at a time on the screen (since this is a popular format on social media). Assembly does not support these kinds of customizations - however, they did offer a solution for this that requires custom code post-processing of the API call which we appreciated.
Therefore, while there are a few small drawbacks, we have been able to accurately deliver speech-to-text recognition to our 180,000+ users thanks to Assembly.
