Sound: 'bh' as in the words 'abhor' and 'subheading' - see note*.
*Note: The sound of the consonant has an implicit 'a' after it so, unless a vowel sound is specified, it will have the implicit 'a' if it has a vowel sound.
It is possible for a consonant to run into the next consonant without an 'a' between them.
