Synthese vocale par concatenation de diphones WORLD — francais

Project description

lectura-tts-diphone

Synthese vocale francaise par concatenation de diphones dans le domaine WORLD.

Installation

# Sans dependances (import seul)
pip install lectura-tts-diphone

# Inference locale (pyworld + numpy + scipy)
pip install "lectura-tts-diphone[local]"

# Avec G2P integre (texte → audio)
pip install "lectura-tts-diphone[all]"

Utilisation

Depuis du texte (necessite lectura-phonemiseur)

from lectura_tts_diphone import synthetiser

audio = synthetiser("Bonjour le monde")
# audio: numpy array float32, 44100 Hz

Depuis des phonemes IPA

from lectura_tts_diphone import creer_engine

engine = creer_engine()
audio = engine.synthesize_groups([
    {"phones": ["b", "ɔ̃", "ʒ", "u", "ʁ"], "boundary": "none"},
    {"phones": ["l", "ə", "m", "ɔ̃", "d"], "boundary": "period"},
])

Controles prosodiques

Parametre Defaut Description
duration_scale 1.0 Vitesse globale (>1 = plus lent)
pause_scale 1.0 Duree des pauses inter-groupes
macro_expressivity 2.0 Gestes prosodiques (0=neutre, 4=exagere)
micro_expressivity 5.0 Micro-variations (0=robot, 10=tres expressif)
spectral_contrast 1.5 Contraste spectral (1.0=off, 2.0=fort)
prosody_style "auto" "declaratif", "question", "exclamation", "suspensif", "neutre"
seed None Graine pour micro-prosodie reproductible

Modes de synthese

  • FLUIDE : lecture naturelle, enchainement continu
  • MOT_A_MOT : lecture mot par mot avec pauses
  • SYLLABES : lecture syllabe par syllabe

Architecture

Texte → [G2P] → Phonemes IPA → Diphone chain
                                      ↓
                              WORLD params (F0 + SP + AP)
                                      ↓
                              Stretch + Concat (overlap)
                                      ↓
                              Prosodie (F0 contour + durees)
                                      ↓
                              GV compensation (contraste spectral)
                                      ↓
                              pw.synthesize → Audio 44100 Hz

Les diphones sont des parametres WORLD (F0 + spectral envelope + aperiodicity) extraits du corpus SIWIS et moyennes par type de transition phonetique.
