What is the difference between speech synthesis and TTS?

Title: Speech Synthesis vs TTS: Understanding the Differences and Choosing the Right One for Your AI Application

Speech synthesis and Text-to-Speech (TTS) are two technologies that allow computers to generate spoken words from text. However, they differ in their approach, capabilities, and use cases. In this article, we will explore the differences between speech synthesis and TTS and help you choose the right one for your AI application.

Speech Synthesis

Speech synthesis is a technique that involves generating spoken words from an audio signal or waveform. The audio signal can be created by recording a human voice or using a digital synthesizer to generate a synthetic voice. Speech synthesis allows for greater control over the tone, pitch, and emotion of the voice, making it ideal for applications such as:

  • Voice assistants: Alexa, Siri, and other virtual assistants use speech synthesis to provide users with audio feedback.
  • Gaming: Speech synthesis can be used to create realistic sound effects in video games.
  • Education: Speech synthesis can be used to help students learn by providing them with an interactive experience that involves listening to spoken words.

Text-to-Speech (TTS)

Text-to-Speech, on the other hand, is a technique that involves converting written text into spoken words. TTS engines use algorithms and machine learning models to analyze the text and generate speech output. TTS can be used in a variety of applications such as:

  • E-books: TTS can be used to convert digital books into audio versions, making them more accessible for visually impaired readers.
  • Audio descriptions: TTS can be used to provide audio descriptions for videos and images, helping people with visual impairments to understand the content.
  • Virtual assistants: Some virtual assistants, such as Amazon’s Alexa, use a combination of speech synthesis and TTS to provide users with audio feedback.

Choosing the Right Technology

When choosing between speech synthesis and TTS, it is important to consider your application requirements and the user experience you want to provide. Here are some factors to consider:

  • Accuracy: If accuracy is critical for your application, TTS may be a better choice as it can handle complex text structures and idioms more accurately than speech synthesis.
  • Customization: Speech synthesis allows for greater customization of the voice, tone, and emotion of the spoken words, making it ideal for applications where you want to provide a personalized experience.
  • Complexity: TTS is generally more complex to implement and requires more data and resources than speech synthesis. However, it can be more efficient once implemented, as it does not require ongoing updates and maintenance.
  • Cost: Speech synthesis can be more expensive to implement, especially if you need a customized voice or want to use a high-quality digital synthesizer. TTS engines can be less expensive, but may require ongoing maintenance and updates.

Conclusion

In conclusion, speech synthesis and Text-to-Speech are two technologies that allow computers to generate spoken words from text. While they differ in their approach and capabilities, both have their own use cases and can provide value for AI applications. By considering your application requirements and the user experience you want to provide, you can choose the right technology to enhance your AI application.
