Switch to Prototype mode.

To define an interaction, click the blue connector on the source object, component state, or artboard. Set the following options in the Property Inspector:

• Trigger: Set to Voice.
• Command: Enter the voice command as text.
• Action: Set to Transition.
• Destination: Set the destination artboard or component state.
• Animation: Set animations based on the available options.
• Easing: Set easing based on the available options.
• Duration: Set the duration in seconds.

To define more than one interaction for an object, component state, or artboard:

1. Select it and click + on it. Alternatively, click + in the Property Inspector.
2. Set the properties in the Property Inspector.

 You can apply Tap, Drag, Hover, and Time triggers only once, and Voice, Keys & Gamepad many times. 

To view the changes you have updated, select the Desktop Preview button .

To preview the transition to the next artboard or component state, hold down the spacebar and repeat the voice command. 

In Prototype mode, select the object or the artboard.

In the Property Inspector, set the following options:

• Click + to add the interaction. 
• Trigger: Set to Tap.
• Action: Set to Audio Playback, and then browse and add the audio file. 

 Auto-play of audio works on Safari only if you have enabled auto-play in Safari settings. To enable auto-play for XD prototype links, see Enable auto-play of sound on Safari.

In Prototype mode, select the object or the artboard on which you want to add multiple actions. 

In the Property Inspector, set the following options:

• Click + to add the interaction. 
• Trigger: Set to Tap.
• Set the first Action + button (transitional action) to Transition, Auto-Animate, Overlay, Scroll To, or Previous artboard. 
• Set the second Action + button (non-transitional action) to Audio Playback or Speech Playback. 
  

 The second Action + button in the Property Inspector is enabled only when you set Tap as the trigger. In addition, if you set a non-transitional action such as Audio Playback or Speech Playback as the first action, the second Action + button is not enabled.

Drag a wire from the source artboard to the destination artboard.

To add a speech playback, in the Property Inspector, set the following options:

• Trigger: Set to Time.
• Delay: Set the time delay (in seconds) to define when the speech playback should start. 
• Action: Set it to Speech Playback.
• Voice: Choose a voice for the speech playback.
• Speech: Type in the text you want for the speech playback.
  

To preview the changes, click the Desktop Preview button .

To preview the speech playback transition to the next artboard, hold down the spacebar and repeat the voice command. 

In Prototype mode, select the Home screen where the start of the flow is set and click the Desktop Preview button.

Select the drop-down arrow next to the record button and select Enable Microphone (macOS). If you are on Windows, enable microphone through an OS-level control in Gamecenter. When recording, watch out for the red icon that flashes on the interface.

Save the recording as an MP4 file, and share it with your stakeholders or post it in social media. 

 This doesn't directly capture audio output from XD, such as speech playback. The mic overhears or records the output depending on the user setup (the system mic would hear the system speakers play the speech playback).

In the desktop app, click the Share icon at the upper right and choose Design Review(for prototypes) or Development(for design specs).

When previewing a prototype on a:

• Desktop or laptop: Hold down the spacebar.
• Adobe XD Mobile app (iOS/Android): Use a long press gesture anywhere on the screen. Place your finger on the screen (without moving it) and use the voice command before lifting your finger back.
• Mobile browser on a smartphone: Hold down the microphone icon in the lower right-corner of the screen.

When previewing design specs, developers can read or view the voice commands and speech playback as text. 

 Design specs do not support voice interactions.
