The freetts tool provides different limitations based on the services offered and the subscription plan of the user. As it depends on the usage package of the user. For free users, they can only convert less than 500 words to the ai speech at a single time. After getting access to the subscription plan, the user can convert up to 5000 words into an impactful ai speech in a single try. However, the freetts ai tools hope to improve and enhance the word limit for speech conversion.
