Phonemic symbols

I don't understand why the phonemic chart in the reference image is different from the phonemic chart you have as the main resource on your website https://www.teachingenglish.org.uk/teaching-resources/teaching-secondar….

I am learning different ways to the English sounds. Thank you very much.

Thank you.
Phonemic symbols will enhance our pronunciation awareness. The study of pronunciation holds significant importance as it enables us to grasp the proper comprehension and articulation of English.

The phonemic symbols are for crucial for professional learners.

It is a very important lesson especially for teachers to find out the correct pronunciation, and reflect on the learners. It is not necessary to let beginners memorize the phonemic symbols but use it as much as possible. It more important for advanced learners to master this.

This material is interesting to share with my students.

This way will help students to read the transcription in the dictionary easily and to be professional in phonology

This is a great learning aid that will be of benefit to me especially and to those who would like to be professional in pronunciation.

It is really useful.

Thanks for efforts. It really helps.

Thanks a bunch

But is there a way to help us combine all these symbol in only one document.
