TTS Regulacja siły głosu w TTS program espeak-NG.

[99teki]

- poniżej program w którym nie potrafię  zmienić wyjścia espeak z i2s na głośność!

- jak ściągamy mp3 z Url to schemat jest taki  UrlStream -> copy-> EncodedAudioStream -> Volume -> I2S.

- proszę o pomoc bo po powodzi klepki uciekły.

- należy wprowadzić poprawki, skala logarytmiczna nie działa.

- dodanie głosu Alicja , no chyba ja jestem głuchy

ESpeak espeak(volume, load_english);
..
volume.setVolume(0.5);				// volume!
