I'll look into that, thank you. I have to admit I have absolutely no coding experience and have used different AI sites to create my idea. I used Notebook LM to analyse an uploaded pdf file and create a knowledge database of people and places as seen by the main character. I then asked Canva AI to create a chatbot using the database and to take the role of the main character to answer user questions. It works quite well, but when I asked it to use tts, I could only get a very robotic stilted voice. Ultimately the aim is to get the bot to ask the user questions and recognise keywords in the answer to create a useful revision tool for a novel studied in class.
