Hello, I want to include SSML support in an text-to-speech software, currently it accepts only pure text with a few variations (rate for instance). But I'm having a lot of difficulty in thinking how to implement a parser for ssml, I'm thinking of Lex and Yacc but that might be an overkill, Isn't there anything simpler?. I cant' find anywhere a detailed document with lexical and sinthatic rules for ssml (like the ones for simplified pascal that computer science students experiment with in computation theory and compilers classes). Can anyone give me a hint on how to implement a parser for ssml? I would be grateful<br>
P.S.: I work at a brazilian company called C.P.q.D., here we have a tts system with natural voice systhesis (portugese and spanish currently) but its lacking support to ssml, here is the link (in portuguese) <a href="https://www.cpqd.com.br/textofala/telefonia/index.htm">https://www.cpqd.com.br/textofala/telefonia/index.htm</a><br>
