DIRECTION

Pronunciation, pauses, speaking style.
Narration just the way you want

AI voice sounds unnatural because of misreadings, intonation, and pauses. With NoLang, you can fix each spot that bothers you, one at a time, until the narration sounds right.

  • Add Pronunciations to the Dictionary

    You can correct the pronunciation of company names and technical terms word by word, using hiragana and katakana. Registered pronunciations are also applied to the videos you create next.

  • Describe the Speaking Style in Writing

    You can choose voices whose speaking style you direct in writing, such as "calm and smooth."

  • Change Speed and Pauses

    You can change the reading speed between 50% and 300%, and adjust the pauses between scenes.

  • Regenerate Only the Scenes You Edited

    Regenerate the audio only for the scenes where you edited the script. The voice in scenes you did not change stays as it is.

DIALOGUE

Solo Narration
or Dialogue Videos

From a script, you can create not only videos with a single narrator but also videos where two or more characters talk to each other.
