Unmixr AI - Text to Speech, Speech to Text, AI Chat(GPT-4o,Claude-3.5) Reviews

I am using Unmixr since two months and i can say that this is the best tool for text-to-speech on appsumo. I am writing this review in context of indian accent of english, hindi & other regional languages. There is lot to improvise. My suggestion is to add template setting for stroy-telling, news, audiobook etc. so that the engine gives best results.

Cons i found is in UI, it lags sometimes, and sometimes it doesnt give output. Also, for some indian voices, there is background noise in the final audio, but it was gone after few regeneration. I am not sure of the reason.
Also, API is not yet available. This restricts any automation you want to do for clients. So, requesting unmixr team to work on this as well. All the best to Unmixr team for future development.

When I do a review, I try to be very honest and objective:

The software is good and useful. It saves you from having to pay monthly subscriptions for other software for tools like "Text to Speech"...

I bought a relatively high tier, and I’ll keep it, as I find it to be a valuable tool to have in my arsenal.

The only problem I see, and this is due to my designer background, is that I am deeply bothered by the interface design and UI it has.

From my designers pov It’s outdated and ugly... We are in 2025... I believe that visual appearance and UI/UX in this era should meet standards of modernity and aesthetics, and I think this is a significant weak point in Unmixr.

It’s such a pleasure when the software is good, and also visually appealing...

I hope the developers can allocate time to improve this aspect, which is one of the most important.

That said, the tool does what it needs to do and is good piece of technology to have.

Overall I am impressed with the sound quality of the provided voices. Cloning of my own voice was straight forward process (under 80 seconds) and the ouput was eerily good. I was primarily testing the TTS capabilites of ePub and PDFs. Simple to upload the doc and generate the mp3. Some suggestions for finesse would include ease of changing the project name and better indication that the mp3 was completed. On screen, it looked like it was perpetually generating, but thankfully - I received an email that it was finished. There is still a lot of rich functionality to further explore - but so far it meets my primary use-case. Thanks team!

Definitely worth every dollar, Unmixr is a tool for everyday use if you create content also had frequent updates and good customer service ......so far it's the best.

This is exactly what I have been waiting for as an elearning developer. One of the best collections of voices available. In addition, I was impressed by the cloning quality.

This product will pay for itself in just one month. What a great deal. Thank you unmixr and Appsumo.
