ElevenLabs is an AI-powered tool that converts text into speech in over 30 languages. It provides settings for voice-overs, sound effects, and multilingual dubbing with customisable voices, adjustable tones, and real-time processing. ElevenLabs supports multilingual content, so it is versatile for various audio projects. Accessing its services requires creating an account. Both free and paid plans are offered, with basic features available for free, and advanced options like voice cloning requiring a subscription. The platform was created by developers Piotr Dąbkowski and Mateusz Staniszewski.
Evaluation: ElevenLabs is a useful resource for creating audio for listening comprehension and pronunciation tasks. Its clear, authentic output speech exposes learners to natural accents, intonation, and rhythm, and sets it apart from similar text-to-speech tools. All in all, it is a time-saving tool for creating audio materials with an intuitive interface. The free version, however, limits users to 10 minutes of audio per month.
Cost: Free limited version with registration + paid options available
