========= eCantorix ========= :: (*) (*) | | |--=====--| | ||||| | | ||||| | ; ||||| : ( ||||| ) \ ||||| / `-=====-' eCantorix is a singing synthesis frontend for espeak. It works by using espeak to generate raw speech samples, then adjusting their pitch and length and finally creating a LMMS project file referencing the samples in sync to the input file. Dependencies ============ * espeak * sox * LMMS * Perl * Config::Tiny * MIDI::Opus * Math::FFT How to use ========== The input file for eCantorix is a slightly more strict MIDI karaoke (.kar) file. Lyrics have to be stored as text events in the same track as the notes associated with them. A lyrics event then covers all notes starting between itself and the next text event. You can use an empty text event to end the range of notes covered by lyrics. In case the range of a lyrics event covers multiple notes, the notes must be all connected (legato), as they will be performed as a single audio sample with pitch shifting. This feature however yields poor quality lyrics and is not recommended - it tends to sound better to rather use separate lyrics events and thus split a syllable into two, like "soft" -> "saw-oft". For polyphony, you can either use multiple tracks (with each having their own instance of the lyrics), or a single track and have the notes placed on multiple MIDI channels (they then will share the lyrics). Once you have such an input file, run:: perl ecantorix.pl -O mmp -o foo.mmp foo.mid The result is a LMMS project file that can be processed to an audio file using:: lmms -o foo.wav --render foo.mmp You can also render to a wave file directly:: perl ecantorix.pl -O wav -o foo.wav foo.mid Also, there is now preliminary support for Vocaloid (VSQ) files. The phonemes are not used yet, though, as doing this would require an external mapping table that depends on the Vocaloid voice in use.
