While AssemblyAI performs exceptionally well, there are a few areas where the developer experience could be further improved. First, regarding native video file support, currently, developers must write custom back-end logic to extract the audio track from video files locally before uploading. If AssemblyAI supported direct native video uploads and handled the audio extraction internally on their servers, it would simplify our back-end architecture. Native real-time status updates could also be improved because while the API is highly stable, writing custom asynchronous polling loops to check transcription status adds boilerplate code. Lastly, the queue latency for micro-files could be optimized because we noticed some initial queue or warm-up latency when transcribing very short audio files under one minute.

Google Cloud Speech-to-Text is not entirely accurate, so we have to correct for those errors in our AI software. It uses neural networks, and that stochastic processing is 70% to 75% accurate. It gets it wrong too often, and since I personally work with this, I don't appreciate that. However, they seem to be the best option currently. We have to write our own improvements because their tools to improve transcription accuracy in our domain aren't very powerful. The timestamp technology for recognized words is inadequate, so we don't use it. We understand words based on their meaning, and we have a whole AI engine that does that, which is one of our differentiators from a product standpoint. We didn't use the custom voice creation feature; we just use their voices, which are fine for our purposes.

Quotes from Members

Pros

"Using AssemblyAI has worked exceptionally well for me because it has helped my team input very little effort to check for quality."
"AssemblyAI impacts my system very well and performs excellently; my users have provided good feedback because I am using AssemblyAI for video transcription and diarization, and it is very fast."
"AssemblyAI has positively impacted my organization because our users started using the chatbot much more from the moment we implemented AssemblyAI in the streaming tool, and usage increased by 300%."
"AssemblyAI has positively impacted my organization as it is in our active pipeline, making it one of the core building blocks of our product that we are currently making."
"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."
"I would suggest others to go for AssemblyAI because it is the best in the market in terms of accuracy, outputs, and the different languages that it caters to and transcribes."
"AssemblyAI has positively impacted my organization because by using it, both our story narrators and story readers benefit greatly."
"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."
"During the time I used Google Cloud Speech-to-Text, it was very impactful to the organization as it made our tasks much easier to perform."
"The implementation is simple, and the outputs are very accurate and crisp."
"Google Cloud Speech-to-Text sounds incredibly natural, which is impressive."
"The product's initial setup phase is very easy."

"Google Cloud Speech-to-Text helps to keep my team more productive."
"You could dictate a bunch of stuff, and then you can get ChatGPT or something to clean it up."
"Creating bots helps our IT team save time."
 

Cons

"AssemblyAI should respond more quickly because when I post a ticket, they take too much time to respond to it."
"AssemblyAI could improve their free tier."
"One area where AssemblyAI can be improved is in summarization."
"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."
"While AssemblyAI performs exceptionally well, there are a few areas where the developer experience could be further improved."
"AssemblyAI needs to be more accurate, particularly with regard to spelling."
"I think the documentation could be improved a bit because it is a little difficult to follow for the first-time user."
"AssemblyAI can be improved in several areas."
"The one thing that I find is when I often use specialized terms, and the solution doesn't know them."
"Google Cloud Speech-to-Text is 100 out of 100 when it works, and when it doesn't work, which is fairly often, it gets a zero. It doesn't fail gracefully; it fails in an unexpected way."
"Given the numerous accents and dialects in India, Google Cloud Speech-to-Text could improve its handling of Indian accents."
"Since it is a paid service, it is very difficult to access if a user does not have the credentials. Also, we have to create the API keys and secret keys repeatedly to maintain authentication and privacy."
"Google Cloud Speech-to-Text's trial experience could be improved by adding some extra minutes in the trial version."
"The tool's telephony model does not produce accurate results."
"Sometimes, speaker diarization is affected, leading to incorrect speaker identification."
"The multilanguage support for the chatbot needs to be better."
