Β According to a new report from Intel Market Research, the global Text to Speech AI Model market was valued at USD 5,026 million in 2024 and is projected to reach USD 13,080 million by 2032, growing at a remarkable CAGR of 16.5% during the forecast period (2025β2032). This exponential growth is driven by rising demand for digital voice assistants, audiobooks, accessibility tools, and multilingual content creation across industries.
Text-to-Speech AI refers to machine learning systems that convert written text into natural-sounding human speech. These models combine deep learning, natural language processing (NLP), and neural voice synthesis to produce lifelike speech with accurate pronunciation, intonation, and emotional expression across multiple languages and accents. Modern TTS AI leverages transformer-based architectures like WaveNet and Tacotron to achieve near-human vocal quality.
