Chennai, Sep 18 (IANS): Filmmaker Jyothi Krishna's wife Aishwarya has made her singing debut in upcoming Telugu action-drama "Oxygen", which stars Gopichand, Raashi Khanna and Anu Emmanuel in the lead.

"I have heard her sing and she has a good voice. In fact, a few filmmakers had even approached her with offers to sing in their films. But she was never interested. When I tested her voice, I really liked what I heard and I thought I should make her sing," Krishna told IANS.

Aishwarya sang two songs in the film.

"One song is a duet and the other one is a family number. Both the songs have come out very well," he said.

Talking about the film, Krishna said high-octane action will be one of the highlights.

"We have about 90 minutes of visual effects, and it took us about four months to complete it. The breathtaking action sequences will be another major attraction. These are the biggest highlights of our film," he said.

Produced by A.M. Rathnam, the film has music by Yuvan Shankar Raja.
