Long-Form Content

Chunked Processing

For content over 5000 characters, split into chunks:

# Process long text in chunks
TEXT="Your very long text here..."

# Split and generate
# Chunk 1
infsh app run infsh/kokoro-tts --input '{
  "text": "<chunk-1>",
  "voice": "bf_emma"
}' > chunk1.json

# Chunk 2
infsh app run infsh/kokoro-tts --input '{
  "text": "<chunk-2>",
  "voice": "bf_emma"
}' > chunk2.json

# Merge chunks
infsh app run infsh/media-merger --input '{
  "audio_files": ["<chunk1-url>", "<chunk2-url>"],
  "crossfade_ms": 100
}'

Speed and Pacing

# Slow narration
infsh app run infsh/kokoro-tts --input '{
  "text": "Take a deep breath. Let yourself relax.",
  "voice": "bf_emma",
  "speed": 0.8
}'

Punctuation for Pacing

Use punctuation to control speech rhythm:

infsh app run infsh/kokoro-tts --input '{
  "text": "Wait... Did you hear that? Something is coming. Something big!",
  "voice": "am_adam"
}'

Best Practices

1. Match voice to content - Professional voice for business, casual for social
2. Use punctuation - Control pacing with periods and commas
3. Keep sentences short - Easier to generate and sounds more natural
4. Test different voices - Same text sounds different across voices
5. Adjust speed - Slightly slower often sounds more natural
6. Break long content - Process in chunks for consistency

Use Cases

• Voiceovers - Video narration, commercials
• Audiobooks - Full book narration
• Podcasts - AI hosts and guests
• E-learning - Course narration
• Accessibility - Screen reader content
• IVR - Phone system messages
• Content localization - Translate and voice
