Can we change the title to "text to speech"?

Thanks.

With an acronym of TTS.

Done.

There are quite a few companies with products to do this. If you do a web search for "tts software" you'll get a lot of hits.

Are there anyone here who tried one of them? And how are Google translate and Bing translator in this area?

Sorry I don't have the time to find the link today, but there was a news report that Google had a device (maybe prototype) that fits in your ear and does real time translation of more than 20 languages.

Considering that we have, Alexa, siri, and Cortana devices everywhere, it is mainstream technology.

In what context/for what purpose? There are different programs/apps for different uses.

I do this: http://www.oddcast.com/home/demos/tts/tts_example.php

I can't explain exactly how our technology works, but we have a variety of backend programs all working together. Some voices are human recorded voices that are parsed and merged, others use neural networks to generate sounds. There is also a significant amount of post-processing that acts sort of like auto-tune since even the best TTS engines can have same harsh artifacts. The technology is fairly old, the current push is to figure out how to do it efficiently on smaller devices like phones.

Just for listening, For example I could listen a story or a lecture note.

What are the some special purposes for this programs?

On your phone or computer? For example, android phones have a native text-to-speech function.

For all devices. Phone, PC and others if there is any. (The devices people have been using are becoming more and more smart in time. Such as cars. So I said others). But mainly for PC.

Sorry, but this question is too broad/unfocused for my taste. I thought you had a specific purpose in mind that I we could help with.

Then it is for PC, I would ilke to turn some texts into speech for just listening to them. But I mean turning them to some file formats such as MP3, this is why I did the title as text to audio. If I turn them into those formats I can listen to them from every device.

Thanks

Any of the links CWatters posted would work. Just hunt around for what you want, some have limits on how much text they're willing to do for free, some don't. I use this for editing because having someone read it to me helps me hear it and computers don't misread like humans do.

Video games, handicapped accessibility, teaching, websites, telephony... it's used for lots of stuff.
 
My car GPS has a "text-to-speech" function as the navigation "voice" reads out the name of the street you shall turn into. Ten years ago, the pronunciation was amateurish and hard to understand, on my last unit it is close to perfect. And Norwegian is not the most common language in the world...
 
I think adobe pdf reader has this feature many years. Have you ever tried it? How is its pronunciation?
