I used to use chat gpt for spanish learning. It was great for a while, but I kept hitting the Advanced Voice usage wall on the Plus tier. If you want to reach real fluency improvement, you need at least an hour of speaking practice a day. On the Plus tier, that is impossible. To get unlimited voice natively, OpenAI wants $2,400 a year for the Pro tier. I did the math on the Realtime API too. At $0.30 per minute (the blended rate for audio input and output), 60 minutes a day for a year costs about $6,570. My math may be off but I've been learning languages with a few different apps and testing to see which ones I like best, and HOW does it even compare to the $80-$100/year these apps are charging??? even with all the other things ChatGPT can do, is 2400 a real number here?? Native ChatGPT doesn't even give me real time feedback on my grammar without a massive system prompt Are these wrappers just better at optimizing the inference costs?"
