|
|
#
|
|

|
|
# stt-dictate start # demarre l'enregistrement
|
|
# stt-dictate stop # arrete et transcrit

#
|
|
# Keybinding i3 (mode toggle):
|
|
# bindsym Mod4+space exec stt-dictate toggle
|
|
#
|
|
# Modeles disponibles (STT_MODEL):
|
|
# tiny - 39 MB - rapide, qualite basique
|
|
# base - 74 MB - rapide, bonne qualite
|
|
# small - 244 MB - equilibre (defaut)
|
|
# medium - 769 MB - lent, excellente qualite
|
|
# large - 1.5 GB - tres lent, meilleure qualite
