News at Eleven: Steve Ember: Frost used the same speaker

for many poems, so the separate poems formed a larger unity. He created this speaker carefully. He felt that his readers would believe his poems if he put the words into the mouth of a wise person who lived in the country, not the city.

Many people thought the speaker was Frost himself. In fact, the speaker was an imaginary person. Frost, the man, tried to become the imaginary person he created for his poetry.
