AI Speech Naturalness Optimization Guide
Podcastle's text-to-speech feature delivers professional-grade results through the following technological innovations:
- Rhythmic modeling techniques: Through millions of hours of voice training, master the four Chinese tones of the pattern of change
- contextual understanding: AI can recognize emotional markers like questions and exclamations in text
- Breathing Simulation: automatic insertion of reasonable gas pauses in long sentences
Enhancement Methods:
- Punctuation optimization: Add exclamation points where emphasis is needed and use apostrophes where there is a change of air
- Speech rate configuration: 150 words/minute recommended for narrative content, reduced to 120 words for important content
- Multi-Version Comparison: Generate 2-3 mixed clips of different timbre versions.
- post-processing: Add slight room reverb (0.8s RT60) to enhance realism
Golden Ratio Recommendation:A hybrid model of real-life recordings of major segments + AI-generated ancillary content (e.g., transitions, ad-libs) works best.
