In the past few years, the AI (Artificial Intelligence) field has improved enormously, as a result of that – you can notice a lot of improvements in some applications such as natural language translator, face recognition software, speech to text or text to speech converting software etc, but it’s still far behind from what we expected.
If you have ever used any text to speech converter or natural language translator then probably you would have been disappointed. I remember, few weeks before – “I was using Google Translate for translating a blog (About some Health Tips from Ayurveda), from English (Source Language i.e the page was written in English) to Hindi (the target language as well as my native language) when I read the translated version of page I couldn’t stop laughing up to 10 minutes (Due to the poor translation it seemed to be a good joke)”.
Similarly when I used ‘espeak’ for converting text to speech, on Ubuntu 11.04 (Natty Narwhal)/10.10 (Maverick Meerkat)/10.04 (Lucid Lynx).. it was just funny (The voice produced by the software was totally different from Human voice, even though it wasn’t so robotic)! i.e not really useful in real world. Anyway, if you are looking for a text – speech converter, then relax, a bunch of free and open source speech synthesizers are available, but most of them just sucks. In this post, you will learn about some best and most popular open source (and of course free) ‘text to speech’ speech software, that you can use on Ubuntu or similar Linux based distributions.
