VoicePicker eases the selection process to grab a particular synthesized voice in OS X, including a way to change the voice language that is far easier than doing the same thing in the Mac’s System Preferences > Dictation & Speech > Text to Speech settings.
Drag. Drop. Speak.
Install VoicePicker on your Mac, then drag the text you want spoken onto the language you want to use. VoicePicker gives you access to a couple of dozen different OS X voices, two genders, multiple dialects, and multiple languages.
Here’s how it looks on the Mac’s screen.
VoicePicker does not come with its own selection of voices, but instead relies upon those already available in OS X and installed on your Mac.
Here’s how it works. Just drag text and drop.
However, other voices are available from Apple that can also be used in VoicePicker, as well as voices from ConvenienceWare. VoicePicker just makes it easier to pick voices than digging into the System Preferences.
