# whisper-live.env
# Configuration for hwdsl2/whisper-live-server on Intel Core i9-13700K (CPU-only)
# Copy this file to the same directory as docker-compose.yml before starting.

# --- Model ---
# 'medium.en' is the sweet spot for CPU-only English meetings:
# accurate, comfortably real-time, ~1.5 GB RAM.
# Upgrade to 'large-v3-turbo' if accuracy is more important than latency;
# downgrade to 'small.en' if you find CPU usage too high.
WHISPERLIVE_MODEL=medium.en

# --- Language ---
# Hardcode to 'en' to skip autodetection — saves ~100 ms per chunk.
# Change to 'auto' if your meetings include other languages.
WHISPERLIVE_LANGUAGE=en

# --- Ports ---
WHISPERLIVE_PORT=9090        # WebSocket (streaming clients)
WHISPERLIVE_REST_PORT=8000   # REST API

# --- Concurrency ---
# 1 simultaneous session is safest for real-time CPU-only use.
# Increase to 2 cautiously — each session competes for the same cores.
WHISPERLIVE_MAX_CLIENTS=1

# --- Session length ---
# 7200 seconds = 2 hours, suitable for a full meeting recording.
WHISPERLIVE_MAX_CONNECTION_TIME=7200

# --- Voice Activity Detection ---
# Keep enabled: VAD skips silence, which meaningfully reduces CPU load
# during pauses and cross-talk at a 12-person table.
WHISPERLIVE_USE_VAD=true

# --- CPU threads ---
# The 13700K has 8 P-cores. Setting threads to 8 gives best single-session
# latency. If you raise MAX_CLIENTS to 2, drop this to 4.
WHISPERLIVE_THREADS=8

# --- Logging ---
WHISPERLIVE_LOG_LEVEL=INFO
