Espeak SAPI/DLL-Nutzung unter Windows?

Question

Frage: Ich versuche, die espeak Text-zu-Sprache-Engine zu verwenden. Also ich habe es funktioniert wunderbar auf Linux (Code unten). Nun wollte ich dieses Basisprogramm in dem Hafen Fenster auch, aber es ist fast unmöglich ...

Ein Teil des Problems ist, dass die Fenster nur DLL für AUDIO_OUTPUT_SYNCHRONOUS erlaubt, was bedeutet es einen Rückruf erfordert, aber ich kann‘ Ich finde heraus, wie man das Audio vom Callback spielt ... Zuerst ist es abgestürzt, dann habe ich gemerkt, ich brauche eine Callback-Funktion, jetzt bekomme ich die Daten in der Callback-Funktion, aber ich weiß nicht, wie ich es spielen soll. Es ist weder eine WAV-Datei noch spielt es automatisch wie auf Linux.

Die Source Website ziemlich nutzlos ist, weil es im Grunde sagt die SAPI-Version verwenden, aber dann gibt es kein Beispiel dafür, wie die sapi espeak DLL verwenden ...

Wie auch immer, hier ist mein Code, kann jemand helfen ?

Answer 1

Haben Sie versucht, das Bestehen der Puffer Sie in Ihrer Callback() zu sndplaysnd erhalten ??

Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long 

Sein Standard winapi ist wie folgt:

sndPlaySound(buffer[0], SND_ASYNC | SND_MEMORY) 

Alternativ kann, wenn Sie eine WAV-Datei, die die Audio-spielen hat:

sndPlaySound(filename, SND_ASYNC) 

Playsound hat eine ASYNC Modus, der die Ausführung Ihres Programms nicht blockiert, während das Audio abgespielt wird.

HINWEIS: Ich habe es in VB verwendet und die obigen Snippets sind für den Einsatz in VB. Wenn Sie in VC++ codieren, müssen Sie sie möglicherweise entsprechend ändern. Aber die Grundabsicht bleibt dieselbe; Übergeben des Puffers an sndPlaySound mit gesetztem ASYNC-Flag.

Gute GLÜCK !!

Answer 2

Mehrere Änderungen im Quellcode sind erforderlich, damit die Windows-Bibliothek dieselbe Funktionalität wie die unter Linux hat. Ich habe die Änderungen here aufgelistet. Die fertige Binärdatei ist ebenfalls verfügbar.

Alle Patches und die Beschreibung wurden auch an espeak maintainer (öffentlich, über die Mailingliste und den Patch-Tracker) gesendet, damit sie in Zukunft vielleicht direkt verfügbar sein werden.
