Today I learned that macOS has an incredible hidden gem: premium downloadable voices that are shockingly good quality, and they’re completely free.
Hear It For Yourself
Here’s Evan (Enhanced) with a quick demo:
Where to Find Them
- Open System Settings
- Go to Accessibility > Spoken Content
- Click the info button next to System voice
- Browse the available voices and click Download on any you want
That’s it. Apple will download the enhanced voice directly to your Mac.
Why This Matters
I used to throttle my usage of voice features to avoid subscribing to paid services. Now I can use these built-in voices as much as I want. They have natural intonation, proper pacing, and less of that robotic quality you’d expect from system voices. It’s not perfect, but it’s free and reasonably fast on M1+.
The Possibilities
This discovery opens up interesting opportunities:
- Local TTS - No API calls, no latency, no costs
- Offline capable - Works without internet once downloaded
- Privacy - Your text never leaves your machine
- Integration - The
saycommand works with any downloaded voice:
# List all available voices
say -v '?'
# Use a specific voice
say -v "Samantha (Enhanced)" "Hello, this is a premium voice"
Combining with Scripts
You can use these voices in shell scripts, automation, or as a fallback when cloud TTS services are unavailable:
# Simple notification script
say -v "Samantha (Enhanced)" "Build completed successfully"
Voice Recommendations
Some voices to try:
- Evan (Enhanced) - Natural American English (used in the demo above)
- Zoe (Premium) - Often cited as the most natural-sounding
- Samantha (Enhanced) - Close to Siri’s default voice
- Daniel (Enhanced) - British English
The enhanced/premium versions are significantly better than the default compact voices. Worth downloading a few to compare.
What I Actually Use
I built Speakeasy to cache calls to API providers like ElevenLabs and OpenAI. I use it to announce Claude hooks and status notifications while I code. It’s still my preferred method, but the built-in voices are a solid free alternative when you don’t need top-tier quality.
