Speechify is absolutely brilliant. Growing up with dyslexia this would have made a big difference. I’m so glad to have it today.

Cmu SPphinx reviews

Sphinx is easy to install and setup and performs surprisingly well without any forced grammar. With PocketSphinx you can easily get some results, enabling you to focus more on configuring sphinx for your project at hand. The support is excellent, both in reaction time (on the forums and the IRC channel) and of high quality.

"The program can't start because MSVCR110.dll is missing" Despite the fact I DO have it installed. This program will waste your time as it doesn't work.

The Telegram group is a great idea, but Nikolay doesnt answer right. Not everybody can dedicate their lifes to "speech recognition". EDIT: I was 2 harsh on him. He is trying his best to help people, even tho , he doesnt have to (join the telegram group and see it yourself) . If you want to use CMUSphinx, do it. But it isn´t the easiest. Thank you Nikolay <3

AssemblyAI reviews

"Great ASR API, even better customer service" What do you like best about AssemblyAI - Speech to Text API? Solid transcription accuracy (we tested a number of competitors and they were the best) with great customer service. Dylan and team go above and beyond. Review collected by and hosted on G2.com. What do you dislike about AssemblyAI - Speech to Text API? This isn't specific to Assembly AI, but transcription accuracy in general (especially with the audio quality of phone calls) can be hit or miss. It just comes with the territory. However, we have been really impressed with how frequently Assembly AI pushes accuracy updates to its models. Review collected by and hosted on G2.com. What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you? Assembly AI transcribes our customers phone calls. Without a solid and reliable ASR vendor, we don't have a product to sell.

"One of the smartest decisions we made!" What do you like best? Changing our transcript provider to AssemblyAI was probably one of the smartest decisions we made. Not only the accuracy is better but they support cutting edge features that can empower your product to do more. We did a benchmark across multiple providers and they were the clear winner. The team is great, super responsive and does a great job keeping us informed about new features and updates. Review collected by and hosted on G2.com. What do you dislike? Nothing that I can recall at the moment. Review collected by and hosted on G2.com. What problems is the product solving and how is that benefiting you? Clean and super accurate transcription + audio intelligence features that make our product shine!

"Most accurate speech to text API" What do you like best? I've tested many stt api's (Google/AWS/IBM) to transcribe audio/video files and AssemblyAI consistently wins on accuracy (lowest WER on our audio files). They also worked with us to get pricing much lower than other api's, and cut our bill from AWS by 50%. Highly recommend for other devs looking for a really simple api/high accuracy. Review collected by and hosted on G2.com. What do you dislike? Along with the rest of the speech recognition industry, there is still a ways to go to get to human level accuracy. Review collected by and hosted on G2.com. What problems is the product solving and how is that benefiting you? Accurate transcription of phone calls and recordings and video interviews.
