# ============================================
# DeepCritical - New Environment Variables
# ============================================
# Add these to your .env file for multimodal audio/image support
# ============================================

# ============================================
# Audio Processing Configuration (TTS)
# ============================================
# Kokoro TTS Model Configuration
TTS_MODEL=hexgrad/Kokoro-82M
TTS_VOICE=af_heart
TTS_SPEED=1.0
TTS_GPU=T4
TTS_TIMEOUT=60

# Available TTS Voices:
# American English Female: af_heart, af_bella, af_nicole, af_aoede, af_kore, af_sarah, af_nova, af_sky, af_alloy, af_jessica, af_river
# American English Male: am_michael, am_fenrir, am_puck, am_echo, am_eric, am_liam, am_onyx, am_santa, am_adam

# Available GPU Types (Modal):
# T4 - Cheapest, good for testing (default)
# A10 - Good balance of cost/performance
# A100 - Fastest, most expensive
# L4 - NVIDIA L4 GPU
# L40S - NVIDIA L40S GPU
# Note: GPU type is set at function definition time. Changes require app restart.

# ============================================
# Audio Processing Configuration (STT)
# ============================================
# Speech-to-Text API Configuration
STT_API_URL=nvidia/canary-1b-v2
STT_SOURCE_LANG=English
STT_TARGET_LANG=English

# Available STT Languages:
# English, Bulgarian, Croatian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish, Swedish, Russian, Ukrainian

# ============================================
# Audio Feature Flags
# ============================================
ENABLE_AUDIO_INPUT=true
ENABLE_AUDIO_OUTPUT=true

# ============================================
# Image OCR Configuration
# ============================================
OCR_API_URL=prithivMLmods/Multimodal-OCR3
ENABLE_IMAGE_INPUT=true

# ============================================
# Modal Configuration (Required for TTS)
# ============================================
# Modal credentials are required for TTS (Text-to-Speech) functionality
# Get your credentials from: https://modal.com/
MODAL_TOKEN_ID=your_modal_token_id_here
MODAL_TOKEN_SECRET=your_modal_token_secret_here

# ============================================
# Existing Environment Variables (for reference)
# ============================================
# These are already documented elsewhere, but included for completeness:

# LLM API Keys (for research agent)
# OPENAI_API_KEY=your_openai_key
# ANTHROPIC_API_KEY=your_anthropic_key
# HF_TOKEN=your_huggingface_token
# HUGGINGFACE_API_KEY=your_huggingface_key

# Embedding Configuration
# OPENAI_EMBEDDING_MODEL=text-embedding-3-small
# LOCAL_EMBEDDING_MODEL=all-MiniLM-L6-v2
# EMBEDDING_PROVIDER=local

# Search Configuration
# WEB_SEARCH_PROVIDER=duckduckgo
# SERPER_API_KEY=your_serper_key
# BRAVE_API_KEY=your_brave_key
# TAVILY_API_KEY=your_tavily_key

# PubMed Configuration
# NCBI_API_KEY=your_ncbi_key

# ============================================
# Usage Instructions
# ============================================
# 1. Copy the variables you need to your .env file
# 2. Replace placeholder values (your_modal_token_id_here, etc.) with actual credentials
# 3. For TTS to work, you MUST configure MODAL_TOKEN_ID and MODAL_TOKEN_SECRET
# 4. STT and OCR work without additional API keys (use public Gradio Spaces)
# 5. GPU type changes require app restart to take effect
# 6. Voice and speed can be changed at runtime via UI Settings accordion
