Description

TextToSpeech (TTS) means:

• grep text,
• analyse it, identify utterances, words, etc.
• phrasing, intonation and durations to words.
• generate the waveform

Goals

• Find a small and fast TTS system with multi language support.
• examine dependencies
• quality check

Status

list of free TTS systems

• festival (to fat)
• flite (festival lite, maybe small enough)
• FreeTTS (java)
• boss (seems not well supported)
• eSpeak

eSpeak

[1]

eSpeak

• is small (350kbyte incl. data)
• fast
• sounds lousy. Nevermind, it is usable.
• supports a lot of languages just now:

Afrikaans, Croatian, Czech, Dutch, English, Esperanto, Finnish, French, German, Greek, Hindi, Hungarian, Italian, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swahili, Swedish, Vietnamese, Welsh

from orca-list 28.juni.2007: "ESpeak is now built against PortAudio v19, so this should mean simultaneous speech and audio playback while using eSpeak under GNOME with Orca."
