QTextToSpeech ¶

概要 ¶

详细描述 ¶

使用 say() to start synthesizing text. It is possible to specify the language with setLocale() . To select between the available voices use setVoice() . The languages and voices depend on the available synthesizers on each platform. On Linux, speech-dispatcher 被使用默认情况下。

暂停当前语音。

注意：

• This function depends on the platform and the backend. It may not work at all, it may take several seconds before it takes effect, or it may pause instantly. Some synthesizers will look for a break that they can later resume from, such as a sentence end.

• Due to Android platform limitations, stops what is presently being said, while resume() starts the previously queued sentence from the beginning.
