Text to Speech

Text-to-speech (TTS) is the synthesis of human-sounding voice from written text — a technology with decades of history (Bell Labs in the 1960s, DECtalk in the 1980s) that became broadly usable around 2018 with neural-network-based voices like Google's WaveNet, Microsoft's neural TTS, and Apple's on-device Siri voices. Modern operating systems ship dozens of high-quality TTS voices free, and the W3C standardized browser access via the Web Speech API. Common use cases: hearing your own writing read aloud (catches awkward sentences and typos), proofreading long documents, quick localization checks, and accessibility — TTS is essential for users with low vision or reading disabilities. This tool wraps the browser's built-in synth in a simple UI. Need to proofread the original text? Use the Word Counter. Want to estimate read-aloud duration? Try the Reading Time Calculator.
