Speak naturally, work faster. Alter’s dictation goes beyond simple transcription with intelligent voice commands and text transformation.

​
Voice Triggers

​

​

Best Practices

Choose words that are easy to say and distinguish
Voice triggers work great with text selections or current app context
Voice triggers use speech-to-prompt (hold to speak), making them perfect for quick voice-activated workflows.

​
