How to Dictate in Multiple Languages on Mac — Complete Guide

If you work in multiple languages, most dictation apps make you manually switch every time. It's annoying. Whisperer lets you set up per-app language profiles, so your IDE uses English while your email uses French. No manual switching.

Pick your language explicitly#

Auto-detection is convenient but it makes mistakes. Especially with:

  • Short phrases (not enough data to guess from)
  • Similar-sounding languages (Spanish vs Portuguese)
  • Mixing languages in one sentence
Info

Explicit language selection is about 10-15% more accurate than auto-detect. Worth setting up.

Different languages for different apps#

Pro Pack lets you assign languages per app:

  • VS Code / Cursor: English for code
  • Pages / Word: French for documents
  • Mail: German for correspondence
  • Slack: English for team chat

Switch apps, language switches automatically. No toggling.

Translate as you dictate#

AI post-processing has a Translate mode. Speak in one language, get text in another. All offline.

  1. Enable AI Post-Processing in Settings
  2. Select "Translate" mode
  3. Set your target language
  4. Speak in your native language, get output in the target

Good for:

  • Writing in a language you speak better than you type
  • Quick translations without switching apps
  • Using personal dictionary terms for consistent translations

Which backend for which language#

BackendLanguagesNotes
Whisper99+Only option for less common languages
NVIDIA25Fastest, but limited coverage
Apple SpeechSystem languagesWhatever Apple supports

If you need Romanian or Icelandic or something uncommon, Whisper is your only choice. For English, Spanish, French, and other top languages, NVIDIA is faster.

Making non-English work better#

  1. Use bigger models. Tiny and Small struggle with non-English. Medium or Large V3 are noticeably better.
  2. Add prompt words for names and technical terms in your language.
  3. Fix recurring mistakes with dictionary corrections.
  4. Set language explicitly instead of relying on auto-detect.

Getting started#

  1. Download Whisperer
  2. Settings, select your language
  3. Set up per-app profiles if you use multiple languages
  4. Full details on multilingual features
