Text blocks
Each block becomes its own audio file. Gemini has a limit of 3900 characters per block, so large text files need to broken up where there are natural breaks. Be aware! Gemini can change the voice slightly between blocks so the 'speaker' may not always sound exactly the same.
Google charge us for each audio file created, so don't go crazy or you'll be sent the bill.
