The actress, who has crooned a number of tracks like "Aazma - luck is the key", decided to support the campaign called Teach AIDS to spread the word especially among youth.

The online campaign will be launched in collaboration with video-sharing site YouTube soon. Shruti has given her voice in three languages to the animated video campaign, which spans information across all aspects of AIDS in a conversational manner.

The video will be available in  English, Tamil and Telugu. "Shruti is someone who is considered to be a youth icon. Hence, when she was approached by the team to lend her voice to the campaign, it fit right in, simply because she had to build awareness for a cause she truly believes in and had to be herself while doing this," said a source.

The actress, who is tied up with her work commitments in Bollywood and southern film industry, managed to take some time out for a good cause. Shruti has also sung for Arjun Kapoor starrer -"Tevar" track "Joganiyan", which has garnered positive reviews.
