Ratings and reviews

The type of device/OS you're using will determine whether your experience is good or bad. On Android, this is at best average. File import/TTS work with local Android voices. Can't get Microsoft Azure to work even with the correct API key, region. I can see the voices, but never works. I also tried on an iPhone with the same API key and it worked. Something is wrong with the Android app and connecting to Azure. Also, iOS has Google AI setup options. I can't rate this higher until Azure is fixed.

hello. I have been using speech Central for a few years now. currently on Pixel 6. your recent upgrade (was it late 2025?) has really thrown a wrench in main use of the app. I can no longer figure out how to edit my pasted text. I listen to PDFs that don't read properly when imported directly, so I have to copy paste them. do I have to upgrade to get this feature back? POSTSCRIPT: THANK YOU SO MUCH FOR YOUR QUICK REPLY. I did not know about that long press feature. That fixed my whole problem

came back to it after a few months and they totally redid the app. it's super ugly now, and everything thing is different, I managed to find the old voice I used, but it keeps switching back and forth between the normal voice and an electronic sounding one. it's super jarring. why the heck did you change the entire app? No one asked for that. it's unbearable. ever hear the saying if it's not broken don't fix it? well, it wasn't broken and now it is. it's extremely upsetting.
