VoiceOS builds a dynamic ASR dictionary from two sources:
  1. terms extracted from messages
  2. terms explicitly passed in dictionary
The two lists are merged and deduplicated before ASR.

​
When to pass dictionary

Pass explicit dictionary terms when you already know the critical terms: 
-F 'dictionary=["VoiceOS","providerFallback","VOICEOS_TEAM_API_KEY"]'
This is useful for:
  • account names
  • product names
  • customer names
  • medical, legal, or financial terminology
  • model names
  • environment variables
  • API names

​
When messages are enough

If the message stack already contains the important terms, VoiceOS can extract them automatically: 
[
  {
    "role": "user",
    "content": "Please update getAsrRoutingDecision and add observability tags for providerFallback."
  }
]
Likely extracted terms: 
[
  "getAsrRoutingDecision",
  "observability",
  "providerFallback"
]

​
Keep terms concise

Good terms:
  • QdrantVectorCache
  • LangGraph
  • TestDashboardApp.tsx
  • api.voiceos.dev
Less useful terms:
  • long paragraphs
  • generic words like dashboard, request, conversation
  • phrases that are not likely to be spoken

​
Provider notes

VoiceOS forwards the merged dictionary in a provider-compatible format. Provider-specific limits vary by backend mode (batch vs realtime), so keep terms concise and prioritize the highest-signal entries.
