The voice of a story in English usually refers to the style or tone in which the story is told. It could be serious, humorous, or something in between.
Shigaraki is not dead in the manga. The storyline has many twists and turns, and his character plays a significant role, so his survival adds to the ongoing drama and suspense.
I would recommend 'The Adventures of Sherlock Holmes'. The stories are full of mystery and intrigue. The characters are vividly described, and the plot twists keep you hooked. The English voice for this, if you can find a good audiobook version, really brings the Victorian London setting to life.
