Automated multilingual call transcription has transformed accuracy and reduced manual effort
The best features AssemblyAI offers are its blazing fast transcribing skills and accurate results. It also has the capability of diarization, as well as transcribing in multiple different languages, both in foreign and Indic languages. I particularly value the accurate transcription of the language that the user provides as input and getting the best output without any kind of noise or silence. Automatic silence removal and voice activity detection are the best features of AssemblyAI that I appreciate in my daily use. The outputs are really accurate. AssemblyAI already cares for the overall grammar, syntax, and the different nuances of the particular speakers. I believe the accuracy part has improved significantly from the previous versions that were available and should continue to improve further to become the best product in the market. There was a saving of about 40 to 50% in transcription of audio analytics calls because previously, it was all done by humans, which could take days of effort and cost. This has significantly reduced to a great amount. We tested with Deepgram and AWS transcription service that is already available in the market, and then we switched over 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.

Pros

"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."
"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."
"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."
"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."
"The implementation is simple, and the outputs are very accurate and crisp."
"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."
"Creating bots helps our IT team save time."
"Google Cloud Speech-to-Text sounds incredibly natural, which is impressive."
"Google Cloud Speech-to-Text helps to keep my team more productive."
"I would suggest Google Cloud Speech-to-Text to others, primarily for the speaker diarization feature."
"We've found the solution scales well."
"The product's initial setup phase is very easy."
 

Cons

"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."
"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."
"I think the documentation could be improved a bit because it is a little difficult to follow for the first-time user."
"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."
"Google Cloud Speech-to-Text's trial experience could be improved by adding some extra minutes in the trial version."
"The multilanguage support for the chatbot needs to be better."
"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."
"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."
"The tool's telephony model does not produce accurate results."
 

Pricing and Cost Advice

Information not available
"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."
