One of the less used and nearly as unknown but increasingly cool features on the Mac is the variety of voices available to read text. Picking those voices or getting more voices to use is a bit convoluted, though.
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. Talk.
Install VoicePicker on your Mac from the App Store, then drag the text you want spoken onto the language you want to use. VoicePicker gives you access to a couple of dozen different macOS High Sierra 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 onto the language you want.
Not enough voices on your Mac?
More 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.
