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.

Support challenges persist despite audio technology advancements
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

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"AssemblyAI has positively impacted my organization by being very helpful for audio transcription, saving time, and helping me find meeting notes."
"After shifting to AssemblyAI, the biggest two points we experienced were that the speed of our software increased and our costing of the API reduced."
"Using AssemblyAI ensured the transcript was highly accurate, meaning that the final educational tools generated by our LLM were of professional academic quality."
"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."
"Because of AssemblyAI, we were able to envision something that could speak naturally to mass consumers."
"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 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."
"Creating bots helps our IT team save time."
"The product's initial setup phase is very easy."
"Google Cloud Speech-to-Text sounds incredibly natural, which is impressive."
"The implementation is simple, and the outputs are very accurate and crisp."
"I would suggest Google Cloud Speech-to-Text to others, primarily for the speaker diarization feature."
"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."
"Google Cloud Speech-to-Text helps to keep my team more productive."
"We've found the solution scales well."
 

Cons

"I believe the streaming process accuracy should improve, and I also wish for a proper application for normal users, not just for developers, so they can easily convert audio."
"I wish AssemblyAI could improve its multilingual support, as it did not work well when I spoke in different languages."
"AssemblyAI could be improved because the accuracy drops noticeably with a heavy accent or a very fast speaker, and pricing can become expensive at a high volume, so better multi-support or more affordable enterprise pricing tiers would make it significantly more competitive."
"While AssemblyAI performs exceptionally well, there are a few areas where the developer experience could be further improved."
"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 should definitely cater to multiple different languages of the world as well as in India."
"Given the numerous accents and dialects in India, Google Cloud Speech-to-Text could improve its handling of Indian accents."
"Sometimes, speaker diarization is affected, leading to incorrect speaker identification."
"The multilanguage support for the chatbot needs to be better."
"The one thing that I find is when I often use specialized terms, and the solution doesn't know them."
"The tool's telephony model does not produce accurate results."
"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 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."
"Google Cloud Speech-to-Text's trial experience could be improved by adding some extra minutes in the trial version."
 

Pricing and Cost Advice

"The tool's cost is also very low. The tool is cheaply priced. It charges around 0.13 INR per call with a duration of five minutes."
"Cost-wise, I would say it is all-inclusive in the payment made to Google."
