Question

Tell application "System Preferences" 
    set "default voice" to "Agnes" 
end tell

结果是：

无法将“默认语音”设置为“anna”。不允许访问。

Answer 1

您的方法存在两个问题：

System Preferences应用程序的字典不包含default voice元素或任何其他元素，用于更改TTS（文本到语音）默认语音（从OS X 10.11开始）;事实上，似乎 Apple没有提供更改默认语音的编程方式（甚至不是通过其NSSpeechSynthesizer Cocoa类。）
通过双引号default voice，您尝试为字符串文字分配一个值，该值始终会失败。

^{注意：此答案的早期版本指向Dropbox位置中名为voice的Bash脚本;此脚本已重命名为voices，修改了其语法，现在已正确发布为开源项目 - 见下文。}

不幸的是，从OSX 10.11（El Capitan）开始，没有记录的编程方式来更改默认语音。

可以这样做，但这样做需要在未记录的系统内部，因此未来的兼容性无法保证。

voices是我写的一个CLI就是这样 - 经过验证可以在OSX 10.11上运行到OSX 10.8。

然后，您可以从AppleScript执行以下操作：

do shell script "/path/to/voices -d {voiceName}"

例如，如果您将voices放入/usr/local/bin并希望切换为Agnes作为默认语音，请使用：

do shell script "/usr/local/bin/voices -d Agnes"

如果您碰巧安装了Node.js，可以安装voices 到/usr/local/bin

npm install voices -g

否则，请按照instructions here。

Answer 2

~/Library/Preferences/com.apple.speech.voice.prefs.plist的更改似乎会立即应用。

d=com.apple.speech.voice.prefs
if [[ $(defaults read $d SelectedVoiceName) = Kathy ]]; then
  defaults write $d SelectedVoiceCreator -int 1835364215
  defaults write $d SelectedVoiceID -int 201
  defaults write $d SelectedVoiceName Alex  
else
  defaults write $d SelectedVoiceCreator -int 1836346163
  defaults write $d SelectedVoiceID -int 2
  defaults write $d SelectedVoiceName Kathy
fi

使用UI脚本的另一个选项：

tell application "System Preferences"
    reveal anchor "TTS" of pane "com.apple.preference.speech"
end tell
tell application "System Events" to tell process "System Preferences"
    tell pop up button 1 of tab group 1 of window 1
        delay 0.1
        click
        if value is "Alex" then
            click menu item "Kathy" of menu 1
        else
            click menu item "Alex" of menu 1
        end if
    end tell
end tell
quit application "System Preferences"

如果系统偏好设置之前未打开，则没有延迟，值为Loading Voices…。

要让它与Yosemite一起使用，您需要将以下两行添加到上面mklement0提供的脚本的底部：

添加以下两行以重新启动SpeechSynthesisServer，否则您无法使用快捷键立即访问新的默认语音：

killall SpeechSynthesisServer
open /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/SpeechSynthesis.framework/Versions/A/SpeechSynthesisServer.app

Answer 4

这是有效的：

property currentVoice : "Vicki"

set systemVoices to {"Agnes", "Albert", "Alex", "BadNews", "Bahh", "Bells", "Boing", "Bruce", ¬
 "Bubbles", "Cellos", "Deranged", "Fred", "GoodNews", "Hysterical", "Junior", "Kathy", ¬
 "Organ", "Princess", "Ralph", "Trinoids", "Vicki", "Victoria", "Whisper", "Zarvox"}

    repeat

     activate me

     set theResult to display dialog "Say What?" default answer ¬

      "" buttons {"Quit", "Speak", "Change Voice"} ¬

      default button "Speak" cancel button "Quit"


if button returned of theResult is "Quit" then exit repeat

 else if button returned of theResult is "Change Voice" then

  set currentVoice to item 1 of ¬

(choose from list systemVoices with prompt "Choose new voice.")

 end if

 if text returned of theResult is not "" then

  say text returned of theResult using currentVoice volume 1

 end if

end repeat

更改默认的文字转语音
