Real-time TTS implementation for educational scenarios
In order to realize real-time voice feedback for teaching scenarios, the following technical solutions can be used:
- Delayed Optimized Configuration::
"`javascript
// The following combination of parameters is preferred:
device: 'webgpu',
dtype: 'fp32',
chunk_size: 512 // control processing granularity
“` - double buffering strategy::
1. Split input text into queues by sentence
2. Use Web Worker to preload the next paragraph
3. Immediate buffer switching at the end of the current paragraph playback - Visual feedback::
- Analyzing the Speech Spectrum through the Web Audio API
- Synchronized display of current read-aloud text highlighting
- Add a progress bar to show generation status
Typical application scenarios: When practicing foreign language reading, it can realize the voice feedback delay within 200ms to achieve the near real-time interaction effect.
