Smart Caching Technology

The feature that saves you 50-75% on TTS costs

How It Works

  • We hash each text chunk to create a unique ID
  • Same text = same hash = same cached audio file
  • Common phrases get generated once, played everywhere

Example Calculation

  • Growth plan: 10,000 credits/month (1M characters)
  • With 60% cache hit rate: ~2.5M effective characters
  • Average blog post: 2,000 characters
  • Result: 625+ articles per month
"ProSpeaker's intelligent caching reduces TTS costs by 50-75% compared to typical usage-based pricing models."
