What is Speech Synthesis?
Speech synthesis is the artificial production of human speech using computer algorithms. Traditionally known as text-to-speech (TTS), this technology converts written text into spoken audio, enabling machines to "speak" in a natural, human-like voice.
Key applications of speech synthesis include:
- Creating accessible content for visually impaired users
- Generating voiceovers for media, marketing, and e-learning
- Powering virtual assistants and chatbots
- Producing automated announcements and alerts
With advances in AI, modern speech synthesis now delivers hyper-realistic, expressive, and multilingual audio—making it an essential tool for creators.
