Her mother, a homemaker, influenced Chauhan to pursue a career in music. She also has a younger sister. At the age of four, Chauhan started performing at competitions and local gatherings, subsequently convinced by her father's friends to take singing seriously. During that time, she was doing live shows and trained herself with "regular riyaaz by listening to cassettes and CDs of popular numbers".
She did her studies from Greenway Modern School and used to stay with her family members in Dilshad Garden, Delhi. She discontinued her studies right after schooling to pursue a career in the music industry. She said: "I quit because I did not feel like studying. I made the decision to pursue my dream as a singer and I don't regret it one bit".
When actress Tabassum spotted her, she made her sing live in her show Tabassum Hit Parade and asked her family to shift to Mumbai. She then introduced Chauhan to Kalyanji Virji Shah and Anandji Virji Shah. Upon meeting, Kalyanji changed her name from Nidhi to Sunidhi as he felt that it is a lucky name. When she was 11, her dad quit his job and brought her to Mumbai. Initially, the family had financial difficulties in adjusting life to the city. After that she worked in Kalyanji's academy for few years and became the lead singer in his "Little Wonders" troupe. She was then offered many shows, though her father insisted on her singing for films.

Chauhan received another Filmfare nomination for Best Female Playback Singer for "Mehboob Mere". She was also heard in Shankar–Ehsaan–Loy-composed folksy flavoured "Bumbro" from Mission Kashmir, which was promoted from being a "background song into the foreground" because of "its beauty". The director of the film, Vidhu Vinod Chopra, wanted an innocent voice for the song when he roped Chauhan to sing for Preity Zinta. According to Chopra, "Chauhan could sound very girlish. So she sang the song with that slightly broken voice."
In 2001, Chauhan was featured in four tracks from the album of Ajnabee. Mandeep Bhara of PlanetBollywood described her rendition of Adnan Sami-duet "Mehbooba Mehbooba" as effortless, when talking about her Kumar Sanu-duet "Meri Zindagi Mein Ajnabee" he said "Sunidhi Chauhan adds pure electricity to the song with her sizzling rendition leaving Kumar Sanu struggling to make an impact". Both the songs were highly successful and highlighted Chauhan's versatility. "Meri Zindagi Mein Ajnabee" was her first romantic song.

One of the dance numbers released during the year was "Aisa Jadoo" from Khakee composed by Ram Sampath, followed by "Ishq Kabhi Kario Na" and "Saaki" from Musafir. Reportedly, Sampath asked Chauhan to stand two feet away from the mike while recording the song "Aisa Jadoo", as the "equipment couldn't handle her pumped-up voice throw." In her review of Musafir, Verma wrote: "Chauhan's husky vocals do complete justice to "Ishq Kabhi Kario Na" by adding just the right amount of sauciness and oomph."

Apart from rendering two soft tracks, "Mere Haath Mein" and "Dekho Na" for Jatin–Lalit composed Fanaa, Chauhan voiced for the remixed track of "Yeh Mera Dil" which was originally sung by Asha Bhosle. According to Rediff.com; "The usually confident Sunidhi Chauhan appears to be conscious of inevitable comparisons to Asha Bhosle's version of the same". The song was met with mixed reactions; some people considered her voice more huskier than it requires, while other complimented her vocals.

In a review from Rediff.com, Raja Sen wrote; "The two-sister song works, from moustache-and-cow similes to paan spits to a fantastic 3–2–1–2–7–2 count, the female vocalists doing the upbeat words justice". However, he found "Kachchi Kaliyaan" from the same film less appealing with its "bad remix background" though praised Chauhan, Ghoshal, KK and Nigam for giving the song the "required vim". Besides, she recorded the soft romantic melody song "Hey Shona" for Vishal-Shekhar for whom she performed "Pyaar Ki Yeh Kahani" and "Sajnaaji Vaari Vaari" from Honeymoon Travels Pvt. Ltd., which resulted in another Filmfare nomination along with "Aaja Nachle".

The "foot-tapping number" became popular at weddings that were scheduled soon after the film. She was next heard in Rahman's traditional tuned "Tu Kuja" from Highway.

She contributed to the album of Jab Harry Met Sejal by performing "Radha" with Shahid Mallya and "Butterfly" alongside Aman Trikha, Nooran Sisters and Dev Negi.

She was next heard in a duet with Sukhwinder Singh; "Bakheda" from Toilet: Ek Prem Katha.

Also, she recorded the anthem of 2017 AIBA World Boxing Championships, a song mix of Hindi, English and Assamese lyrics blended with a rap performed by her.
Chauhan possesses a high octave vocal range, and has the ability to reach lower octaves and dropping notes with transition. The Indian Express described her as a soprano, though criticising her "high-pitched non-falsetto voice because of the "squeakiness it acquires while belting out those notes". Lata Mangeshkar who described Chauhan's vocals as "different" from her contemporary, mentioned that her voice will not suit musical style of lori. Lyricist Prasoon Joshi described Chauhan as an effervescent and soulful singer who can lend her voice to any situation. Director Ram Gopal Varma calling her an extraordinary talent, said "I think it’s the various facets of her personality, that is so full of life and energy, which come through in a musical way in her diverse songs". Chauhan has the ability to change her tonal quality with a lot of ease and charisma. According to Rajani Kanikar, she has a "powerful" and "husky" voice which she attributes to her father. Music composer Amit Trivedi considers Chauhan to be the most versatile female singer after Asha Bhosle who is good with all the genres. She feels that her vocals structure suits on Priyanka Chopra, Katrina Kaif, Kajol, Parineeti Chopra and Urmila Matondkar the most. According to The Daily Star, "be it a soft classical-like piece or an operatic pitch, Chauhan is spectacular with her vocals". Though she has performs in high-pitched vocals songs, she is known for her "deeper pitched voice", on which Ajay Gehlawat wrote: "Chauhan's deeper timbre replaces Asha Bhosle's higher pitched vocals" in the song "Yeh Mera Dil", ensuring such "fuller female timbres become more commonplace' to a decidedly more forceful and sensual sounds". Ganesh Anantharaman in his book Bollywood Melodies: A History of the Hindi Film Song wrote that Chauhan has a "good, expressive" voice but she crafted a particular image for herself as the singer of fast, racy songs.
The Times of India considered her voice as the "liveliest voice in Bollywood". According to MensXP.com, "her voice is orgasmic and extremely fierce. While singing a certain stanza, she gets into the mood so deeply, her voice breaks into a passionate squeal as she strikes a high note". In an interview, classical musician Rahul Sharma said, "Chauhan's voice has an element of sensuality which [is] also very versatile and I admire the quality of her voice and the kind of emotions she can bring out".
Chauhan's music contains elements of pop, hip hop and R&B. Music composer Sandeep Chowta while talking about the singer said "She is a brilliant singer with a wide range and an individual style. She does not copy anyone. She knows what she’s doing and is in total control. She’s not just a singer, she’s also a musician". Chauhan has said that her audience feels more comfortable in hearing her singing item songs and she made her "name because of that genre". The perception of singing only item songs was "broken" when Chauhan performed the romantic song, "Meri Zindagi Mein" for Anu Malik which was then followed by songs from Chameli and Fanaa. However, Chauhan declared that she "dislikes" tagging songs as item numbers and "they are treated specially, they have extra attention and they are picturised in a special way. So, I like being associated to any special song".
Describing her singing style, Chauhan said; "I have no particular style; instead I only go with the music and the lyrics, and feel free to express my emotions through singing".

Believing that singing all kinds of songs makes her grow as a musician she revealed that her "weakness remains for soft melodies".
