Lee collaborated with the film's score producer Michael Wandmacher and director Eric Dennis Howell, with whom she got acquainted to Voice from the Stone and its plot.

Musically, "Speak to Me" is a piano ballad instrumentally complete with strings, booming drums and cellos, and is lyrically from the perspective of the deceased protagonist communicating to her child.

It serves as a parallel backstory to the film, and features Lee singing and playing the piano near an ancient castle and scenes of her walking in the surroundings with a boy.

[4] In August 2015, it was revealed that Lee would write music for the ending credits of the independent film Voice from the Stone, directed by Eric Dennis Howell.

Closely related with both the director of the film, Eric Howell, and the composer of its musical score, Michael Wandmacher, Lee had a conversation with both and "felt a surge of inspiration and immediately began writing" shortly afterwards.

In the film, the mother's character is a classical singer and a piano player who also enjoyed the perks of motherhood; Lee expressed her compatibility with the given description, saying, "There is no way that this could have been more me!

[10] Vanessa Vallon, writing for the website AXS noted that "Speak to Me" served as a demonstration by Lee of her "versatility"; she further described her vocal performance on the song as "gorgeously plead[ing]".

[12] Mike Wass from the music blog Idolator, deemed the song to be "strikingly beautiful" and noted how it "evokes the gothic drama and emotional intimacy of 'My Immortal'".

[13] Music Week journalist Ben Homewood felt that it would be an understatement to say that the song's usage in the trailer for the film "heightens the drama on display".

[14] Writing for LemonWire, Jessica Tamez praised Lee's vocals, describing them as "liquid gold to say the very least" and adding that she managed to convey the same "intensity and beauty" characteristics of all her work.

Tamez went on to praise the singer for her ability "adequately capture the depth of a situation and magnify that with such elegance [which] distinguishes her amongst fellow artists" and observed that the melody of "Speak to Me" managed to be a fitting accompaniment to the film's profundity.

Lee collaborated with Howell on the video and they both imagined it as a "parallel and backstory to the film" which explores the relationship between the main protagonist and her son and the notion that "love is stronger than death".
