Besides playing the recording every day (the recording will be learned once a week), you must spend more time with him and teach him. After all, what you have worked so hard to cultivate is definitely different from what you heard on the tape. If possible, find a talking stork to raise with him. Bird teaching must be much faster than human teaching. Absolutely effective. Storks have strong imitation ability. You can put a mirror next to the cage without conditions, which can also play a similar role. The most important thing is persistence. My myna can speak more than ten words now. Come on!
