Overview Guide
Primary Text to Speech Synthesizing and Playback Duration Models (Standard Acoustic Timing Method):
| Synthesized Playback Metric | Conversion or Mathematical Equation | Formula Variables Defined |
|---|---|---|
| Playback Duration (Durationsec) | Durationsec = WordCount ÷ (SpeechRate ÷ 60) | WordCount: Total count of words in synthesis text. |
| Acoustic Output Frequency | Freqtarget = Freqbase × PitchFactor | SpeechRate: Speaking speed rating (words per minute). |
| Character Processing Speed | CharsPerSecond = CharsCount ÷ Durationsec | PitchFactor: Scale multiplier shaping acoustic tone. |
| Speech Synthesis Output | Waveoutput = Synthesize(Text, Rate, Pitch) | Waveoutput: Resulting synthesized audio stream. |
Formula Variables Defined:
- WordCount: The total number of words contained within the input synthesis text.
- SpeechRate: The speed parameter setting, measured in WPM (typically 120 WPM to 200 WPM).
- PitchFactor: The acoustic pitch offset factor, modifying voice tone frequencies.
- Durationsec: The calculated playback time duration in seconds.
Formula Breakdown: Converting text characters into spoken audio streams requires calculating acoustic playback time. By dividing text word counts by speech rate factors (calibrated in WPM) and multiplying by pitch coefficients, the synthesizer calculates final playback durations. Audio waveforms are outputted in real time locally.
Step-by-Step Explanation: To convert text to speech, input your text. Select your preferred voice, speaking speed rate, and pitch factor. Click the speak action, and the system synthesizes the letters into spoken audio streams locally in your browser.
Practical Example: A text block of exactly 300 words is synthesized at a speaking rate of 150 WPM. The estimated playback duration calculates as: Durationsec = 300 ÷ (150 ÷ 60) = 300 ÷ 2.5 = 120 seconds. The spoken audio plays smoothly over exactly 2 minutes.
