How Many Characters Is 1,000 Words?
1,000 words in English is roughly 5,500-6,000 characters, including spaces. The average English word is about 4.7 letters long; add one space per word and round for punctuation, and you land in that range. It varies with your actual vocabulary: technical writing with longer words runs higher, simple text runs lower.
Why TTS tools measure in characters, not words
A "word" isn't a consistent unit: "cat" and "responsibility" are both one word but very different amounts of audio to generate. Characters are the actual input the underlying model processes, so limits and pricing based on characters are more predictable than limits based on word count would be.

What this means for your daily limit
On HixCodeTTSv1, free accounts share 5,000 characters a day (roughly 909 words), split across as many requests as you like; paid requests go up to 12,000 characters per request, roughly 2,182 words. If your script runs longer than what you have left, split it at natural breaks, paragraph or scene boundaries, rather than mid-sentence, so each generated clip still sounds complete on its own.
