The best features AssemblyAI offers are transcription and real-time transcriptions, and the speed of real-time transcription stands out to me because it's 20 to 40% faster than the industry benchmark, so speed is definitely one of the pros of AssemblyAI.

The primary benefit I receive from their product is much more accurate transcription; first, it is a very affordable service, and second, the accuracy is much better compared to other services such as Deepgram or AWS transcription services, which are the main benefits.

If you are using it for English transcription and your primary goal consists of only English audios, then I recommend it because it is affordable, performs better than alternatives, and has been available for a long time, so customer support should also be good.

AssemblyAI could be improved because when we have different accents on the same call, it usually fails, especially when we have American, Asian, and Latin American speakers on the same call, making the transcriptions a bit noisy.

AssemblyAI should respond more quickly because when I post a ticket, they take too much time to respond to it.

AssemblyAI can be improved; I think they should manage their webhooks better to retrieve my data as soon as possible for my audio.

However, when I try to handle Hindi plus English or Hinglish audios where there is code switching between English and Hindi, then it falls apart significantly.
