* Standard British English: "Hello" with the "h" pronounced clearly.
* Cockney: "**'ello" with the "h" dropped and a strong "l" sound.
* Northern English: "**'ey" with a short, sharp "e" sound.
* Scottish: "Ah" with a slightly raised "a" sound.
The best way to learn to say "hi" with an English accent is to listen to native speakers and try to imitate their pronunciation. You can find many videos and audio recordings online of people speaking in different English accents.
Remember, the goal is to be understood clearly, so don't be afraid to experiment and find what sounds most natural to you!
