Background introduction
TTS is the abbreviation of Text To Speech, which is "from text to speech". It is a part of human-machine dialogue that allows machines to speak.
Ekho is a free, open source Chinese speech synthesis software. It currently supports Cantonese, Mandarin (Mandarin), Guangdong Taishan dialect, Zhao'an Hakka, Tibetan, Yayan (the lingua franca of ancient China) and Korean (under trial), and English is implemented indirectly through eSpeak or Festival. Ekho supports Linux, Windows and Android platforms.
