Full Stack Developer at a tech services company with 11-50 employees
Accurate transcripts with clear grammar have supported reliable speaker-based dialogue analysis
A few drawbacks I observed in the speaker identification are that in some videos where text and names appear on the video frames, AssemblyAI does not identify the actual speaker name, instead providing generic names such as Speaker A, Speaker B, Speaker C, or Speaker X, Y, Z. AssemblyAI does not identify the real speaker in some audio or video files, just sending Speaker A, Speaker B, or Speaker C. They are not easily identifying speakers in some instances. AssemblyAI does not provide a cloud service; I simply upload the audio file to the API, and they store it somewhere internally to send me the transcription text. For additional functions, the API does not provide video uploading functionality, and I need to convert video to audio first before uploading it to AssemblyAI.

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

"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."
"We've found the solution scales well."
"I would suggest Google Cloud Speech-to-Text to others, primarily for the speaker diarization feature."
"Creating bots helps our IT team save time."
"Google Cloud Speech-to-Text sounds incredibly natural, which is impressive."
"The implementation is simple, and the outputs are very accurate and crisp."
"You could dictate a bunch of stuff, and then you can get ChatGPT or something to clean it up."
"The product's initial setup phase is very easy."
"Google Cloud Speech-to-Text helps to keep my team more productive."
 

Cons

"AssemblyAI should respond more quickly because when I post a ticket, they take too much time to respond to it."
"The multilanguage support for the chatbot needs to be better."
"Given the numerous accents and dialects in India, Google Cloud Speech-to-Text could improve its handling of Indian accents."
"The multilanguage support for the chatbot needs to be better."
"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."
"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's trial experience could be improved by adding some extra minutes in the trial version."
"Sometimes, speaker diarization is affected, leading to incorrect speaker identification."
"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."
 

Pricing and Cost Advice
