How Speechgen's Smart Caching Simplifies Text-to-Speech

What Is Smart Caching?

Smart caching in Speechgen is an advanced feature designed to save time and costs during text-to-speech synthesis. By storing and reusing previously voiced sentences, it ensures efficiency and minimizes redundant processing.

Key Features of the Technology

1. Reuse of Voiced Sentences:

   • Speechgen remembers each sentence you synthesize.

   • If you make changes to the text, only new or modified sentences are processed, while the unchanged ones are retrieved from memory.

2. Efficient Combination:

   • The system seamlessly merges new and cached sentences into a single audio file, eliminating the need for complete revoicing.

Benefits at a Glance

• Time Efficiency: Spend less time on repeated voiceovers.

• Cost Savings: Pay only for new content rather than the entire text.

Practical Example

When voicing an educational course, adding a short introduction to each lesson with other services might mean revoicing all lessons. With Speechgen, only the new introductions are voiced, while the original content remains intact and cost-free.

Important Considerations

1. Cache Capacity:

   • The cache applies to texts of up to 100,000 characters.

   • For longer texts, Speechgen switches to a specialized mode for large blocks, accommodating up to 2,000,000 characters.

2. Storage Time:

   • Cached sentences remain available for 7 days.

   • Full voiceover history is accessible in your profile for 30 days.

3. Caching Rules:

   • Only exact matches (character by character) are reused.

   • Minor edits, such as adding or removing punctuation, mark sentences as new and require revoicing.

What Changes Affect Caching?

• Content Edits: Any modification to a sentence, whether it’s changing a word, punctuation, or adding tags like <break>, results in revoicing.

• Voice Settings: Adjusting the speed, tone, or speaker triggers a complete revoicing, as these parameters redefine the audio output.

Adjustments Without Extra Costs

• Pauses: You can modify pauses between sentences or paragraphs without revoicing.

• Format Changes: Switching audio formats (e.g., ogg, wav) or adjusting the sample rate does not incur additional costs.

Why Choose Speechgen?

With smart caching, Speechgen offers unmatched efficiency:

• Lower Costs: Avoid paying for unchanged sentences.

• Speed: Revoicing is faster and more streamlined.

• Flexibility: Edit and refine your projects without worrying about repeated charges.
