Some backstory: By chance whilst visiting Ho Chi Minh city, I tried to create a tongue twister for a Vietnamese girl who spoke perfect English. This one did it.<p>I hadn’t yet asked ChatGPT or any other LLM until now to break down why a very reproducible task (English essentially must be your native language to pronounce this correctly) is near-impossible to do in rapid succession for ESL speakers.<p>I used o1-preview. Afaik, this is a new tongue twister.
