Janaki was born in Pallapatla, a village in the Guntur district of present-day Andhra Pradesh, into a Telugu-speaking family. She received early training in Carnatic music from her maternal uncle and showed an aptitude for singing from childhood, performing at school events and on All India Radio in her teens.
In 1957, she moved to Madras (now Chennai) seeking opportunities in the film industry. She was inducted into the AVM Productions music wing, where she was trained by music director T. Chalapathi Rao. Her audition led to her first playback recording the same year.
Her debut song was for the Telugu film M.L.A. (1957). Around the same period she began recording in Tamil cinema, with early opportunities in films produced by AVM. She gradually established herself in Tamil, Telugu, Kannada, and Malayalam film industries through the 1960s, working with leading composers of the era such as K. V. Mahadevan, M. S. Viswanathan, and G. Devarajan.
From the 1970s, Janaki became one of the most sought-after voices in South Indian cinema. Her long-standing professional association with composer Ilaiyaraaja produced a large body of widely admired songs in Tamil and other languages from the late 1970s onwards. She was also a frequent collaborator of K. J. Yesudas, S. P. Balasubrahmanyam, and P. Susheela in duets.
She worked extensively with composers including Salil Chowdhury, M. B. Sreenivasan, Rajan–Nagendra, M. S. Viswanathan, Chakravarthy, and later A. R. Rahman, among many others. In Hindi cinema, she recorded a smaller but notable set of songs, including for Bappi Lahiri and Laxmikant–Pyarelal.
Janaki has cited a tally exceeding 40,000 songs across multiple languages, although exact discographies vary. She continued to perform stage concerts in India and abroad, particularly across South Asian diaspora communities. In 2016, she announced her retirement from playback singing, while remaining active in occasional concert performances and devotional recordings.
Janaki is recognised for her wide vocal range, control over microtonal ornamentation, and ability to adapt to varied genres including classical, folk, semi-classical, devotional, and Western-influenced film music. She is noted for her diction across multiple languages despite Telugu being her mother tongue, and for emotive renditions in dramatic and tragic compositions. Composers and critics have credited her with elevating playback singing in South India alongside contemporaries such as P. Susheela.
Janaki married V. Ramprasad and is based in Chennai. She has a son, Murali Krishna.
