1. What is TTS?
Text to Speech (TTS) is a technology that converts written text into spoken words. It leverages Artificial Intelligence (AI) and Natural Language Processing (NLP) to generate human-like speech. TTS is widely used in various devices, including computers, smartphones, and smart assistants, making digital content more accessible to users who prefer audio over text.
TTS has evolved significantly over the past few decades, moving from robotic and monotone voices to natural, expressive speech synthesis. Modern TTS systems can now mimic human intonation, rhythm, and even emotional inflection, making them highly effective in various applications.
2. How Does TTS Work?
TTS technology operates through two main processes:
- Text Processing: The system analyzes and converts written content into phonetic representations. It also applies linguistic rules to determine intonation and stress patterns.
- Speech Synthesis: The processed text is transformed into spoken words using AI-powered speech synthesis models, which can either use pre-recorded human voices or deep learning models to create natural-sounding speech.
There are two main types of speech synthesis:
- Concatenative Synthesis: Uses pre-recorded speech segments and stitches them together to form words and sentences. It produces high-quality audio but is limited in flexibility.
- Parametric Synthesis: Uses AI and mathematical models to generate speech dynamically. It offers greater flexibility and customization but requires significant processing power.
