Audio Feedback Options in iOS 12 Shortcuts

Integrating audio feedback into iOS 12 Shortcuts allows users to confirm task completions, receive spoken alerts, and run routines without needing to look at their screens. In iOS 12, the Shortcuts app provides several native actions to produce sound, ranging from synthesized voice notifications to default alert chimes and custom media playback. This guide breaks down the primary methods available for embedding audio cues directly into your workflows.

Speak Text

The Speak Text action is the most versatile audio feedback tool in iOS 12. It utilizes Apple's Text-to-Speech (TTS) engine to read dynamic text, variables, or custom notifications aloud.

  • Customization: You can adjust the speaking rate, pitch, language, and voice within the action settings.
  • Dynamic Data: Place variables directly into the text field to have the shortcut speak out calculation results, weather forecasts, battery levels, or calendar events.
  • Wait Until Finished: This option allows the shortcut to pause execution until the speech finishes or continue running background actions immediately.

Play Sound

The Play Sound action plays a short audio file or alert chime.

  • Default Chime: Placed on its own, it triggers the standard system confirmation alert, making it ideal for signifying the end of a long automation.
  • Custom Audio via Base64: While iOS 12 does not offer a direct sound-picker action, you can embed custom audio files (such as .wav or .mp3 clips). Encode your audio file into a Base64 string, paste it into a Text action, use the Base64 Encode action (set to Decode), and pass the output directly into Play Sound.

Music and Media Playback

For longer audio feedback, the Shortcuts app can trigger audio from your local library or Apple Music.

  • Play Music: Starts playback of a specific song, playlist, or album to serve as a musical confirmation.
  • Play/Pause: Controls active media playback on the device to temporarily pause background audio while other tasks run or to resume music after an alert.

Haptic Pairing

While technically tactile feedback rather than audio, the Vibrate Device action can be paired immediately before or after an audio action. This ensures that the user receives physical confirmation alongside the auditory cue, which is especially useful when running shortcuts in noisy environments or when the device volume is muted.
