Since debuting as a soloist in October 2015 with the successful extended plays I and Why as well as chart-topping digital singles "Rain" and "11:11", South Korean singer Kim Tae-yeon (known by her mononym Taeyeon) has risen to prominence and established herself as the country's most popular individual celebrity of 2016.

[2] A day later, the agency released promotional photos and a short trailer of the music video for a new song titled "I Got Love", which was set to be the album's pre-released track.

[5] The digital edition of My Voice contains 12 songs, while the physical release includes 13 tracks with a bonus titled "Time Spent Walking Through Memories" (기억을 걷는 시간), which is a cover of South Korean indie rock band Nell.

[6] The album incorporates various genres that are "based on Taeyeon's unique vocals", including pop, R&B, and PBR&B.

[11] Three new original songs featured on the deluxe edition are "Make Me Love You", "I Blame on You" and "Curtain Call".

He additionally lauded Taeyeon's "impressive" vocals on the album, which was exemplified by the refrain of the track "Sweet Love".

While considering the album's musical styles as a lack of "cohesiveness" due to its incorporation of multiple genres, Chin argued that My Voice was a "monumental record" as it focused more on Taeyeon's artistry rather than K-pop's common emphasis on "slick boot-camp choreography, powerful visuals and a highly manufactured sound".

[19] My Voice debuted at number two the Billboard World Albums, becoming Taeyeon's second number-two entry on the chart following Why (2016).

Plus, they wrote "My Voice is playful at times and evocative at others as it flits through musical styles, but throughout the listening experience, it is Taeyeon’s crisp vocals that are front and center.

[30] To further promote the album, Taeyeon embarked on a concert tour titled "Persona", kicking off on May 12, 2017, at the Seoul Olympic Park.
