It could refer to an improvement in their vocal tone, pitch, or volume, or to an increased ability to articulate their thoughts and ideas. It may also imply that the speaker is feeling more comfortable with their own identity and is able to express themselves more authentically. In general, the phrase "own voice blossoms" suggests a positive transformation in the speaker's ability to communicate and connect with others.
