-g- is pronounced the same as an English '-g-'
In the the discussion headed 'Pronunciation' , and in the Notes in one of the very early sections of the course, there is a link to some very good videos explaining Welsh pronunciation.
Thank you. I've listened to some of the pronunciation videos , and they help, it's just the computer voice sometimes makes the G sound different.
G on its own is always a hard sound in Welsh, as in 'gate' in English.
The computer voice sometimes makes mistakes, quite often when it pronounces what should be a long vowel as a short one.
Remember also that 'ng' is a separate letter and is the soft sound in 'sing' in English.
