About

Synthesys is an AI voice generation and text-to-speech platform offering 400+ human-like AI voices in 140+ languages for professional voiceovers, video content, and audio production. What distinguishes Synthesys from other TTS platforms is its dual focus: both text-to-speech for standard voiceovers and AI voice cloning that creates a custom digital voice from a short voice sample. Synthesys offers emotional speech controls allowing creators to adjust the tone energy and pacing of generated audio. The platform also includes a video generation feature called Synthesys Studio that combines AI voice with lip-synced animated avatars, enabling talking-head video creation without recording yourself. For content creators, marketers, and businesses producing video content at scale, Synthesys provides an all-in-one voice and video solution. Use cases include YouTube voiceovers, e-learning narration, commercial voice acting, IVR systems, audiobooks, and social media video content. The platform integrates with popular video editing and presentation tools. Synthesys uses advanced neural network models trained on professional voice actor recordings, resulting in natural intonation and rhythm that avoids the robotic quality of older TTS systems. Pricing includes pay-per-project options and subscription plans starting at competitive rates. Compared to ElevenLabs which leads in voice realism, Synthesys offers a broader feature set including video generation and more extensive voice library, making it a versatile choice for content creation teams.
