How to Install TTS Voices in macOS 15 Sequoia

With the release of macOS 15 Sequoia, Apple has changed the way users install additional Text-to-Speech (TTS) voices. By default nearly all Enhanced and Premium quality voices are not installed and this is something that most of experienced TTS users do on their new Mac. If you’re looking for the familiar location under Accessibility → Spoken Content, you won’t find it there anymore. Instead, you now have to install voices through the VoiceOver settings. This change has caused confusion, especially since iOS still uses Spoken Content section for TTS voices install, while watchOS follows the new VoiceOver method.

Where to Install TTS Voices in macOS 15 Sequoia

Follow these steps to install additional TTS voices in macOS 15 Sequoia:

1. Open the VoiceOver Utility. You can do this by pressing VO + Fn + F8 (where VO stands for the VoiceOver modifier, typically Control + Option).
2. In the VoiceOver Utility, select Speech from the sidebar.
3. Click the Voices section.
4. Press the Add (+) button.
5. Select your preferred language and browse available voices.
6. Click Download next to the voice you want to install.
7. Once installed, you can set it as your primary VoiceOver voice.

Why This Change is Confusing

Apple’s decision to move TTS voice installation under VoiceOver is inconsistent across its ecosystem:

• macOS 15 Sequoia: Voices are installed in VoiceOver settings.
• iOS 18: Voices are still installed under Spoken Content in Accessibility.
• watchOS 11: Voices are also managed via VoiceOver.

This inconsistency makes it harder for users to locate voice installation settings across different Apple devices. A more intuitive approach would be a unified “Manage Voices” section under Accessibility on all platforms.
