Find out in this report how the two Speech-To-Text Services solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
There was a 98% cost reduction on transcription because traditional manual human transcription costs a lot, so by using AssemblyAI, the cost dropped significantly.
I have seen a return on investment; I have saved money, time, and needed fewer employees for this project, which I did solo with the help of AI.
Before using other tools for summarization of writers' stories, it took a lot of time, but with AssemblyAI, the time to convert a story into a summary has decreased significantly.
He stated that the performance was significantly higher than elsewhere, and he found it suitable for his needs.
When it comes to the evolution of STT, multiple things are considered. One is the technical offering and accuracy of Deepgram, then ease of integration, and cost of implementation.
It has excellent documentation and SDKs, responsive developer channels, and clear API error messages.
Customer support is definitely great with AssemblyAI.
AssemblyAI should respond more quickly because when I post a ticket, they take too much time to respond to it.
We have extensive support available on Deepgram websites and they have many GitHub repositories.
The most important aspect of the documentation is that it is structured so that AI can read it effectively.
The API is built to handle enterprise-level volumes, which means we can scale from a small local test environment to thousands of active students without making any changes to our back-end code.
It has definitely been integrated in such a way that it handles multiple audios at a time.
The scalability of AssemblyAI for my organization is good as we have a high volume of scale right now, with around 25,000 requests, and it is performing well.
AWS provides higher scalability with 10,000 connections at a single go, despite higher latency than Deepgram.
I'm not sure if Deepgram offers options to choose the server location, such as having a server in Frankfurt like AWS.
Deepgram's scalability has been fine; there were some limit issues with Vapi.
It has a high API uptime; I experienced near-perfect uptime on the public API endpoints.
I have not faced any outages or service failures.
AssemblyAI is quite stable for us.
We have never faced any issues with downtime.
Deepgram has been stable and reliable
Latency is almost zero, and it's 20 to 40% faster than the industry benchmarks.
Healthcare terms, specifically drug terms related to the medical field, drug products, or chemical products, are sometimes misspelled.
I wish AssemblyAI could improve its multilingual support, as it did not work well when I spoke in different languages.
If it had support for many more languages, especially regional languages, it would be valuable.
Considering additional accents from Chilean or Argentine speakers could improve the model's performance with local words.
They also came up with their own agent builder framework, where you can directly go to their website and build your voice agent in 10-20 minutes.
There are no licensing fees, setup costs, or long-term contract requirements.
My competitor Deepgram offers lower cost but does not support my native language.
Regarding my experience with pricing, setup cost, and licensing, I would like to know if it can be reduced somehow.
My experience with pricing, setup cost, and licensing was good, as I found it to be cheaper without any problems.
My experience with pricing, setup cost, and licensing is that pricing is seamless and customizable as needed.
The main features I appreciate in AssemblyAI are that it provides better accuracy compared to other transcription services, with clear grammar and no errors in spelling mistakes or grammatical mistakes, delivering clear transcription.
Usage increased by 300%.
The stream support helped me in an AI interview platform where a candidate speaks, and I see the live transcription of their answers, which is helpful for candidates to identify if their words are correctly captured.
Deepgram has positively impacted my organization by achieving our desired results, which is very good from the overall technology perspective, saving a lot of time for the support team since the voice agent replaced the human agents managing the calls, thus improving response time and reducing the time dedicated by those human agents.
The most valuable capabilities of Deepgram that I've found so far include low latency, as it offers less than 200 milliseconds, which is not provided by any other text-to-speech models.
The best thing with Deepgram is they are continually evolving and doing a lot of market research. They take feedback seriously.
