Recaptcha Audio option is differnt from gmail signup audio option

Hi,I've observed that recaptcha audio is much clear in gmail sign up page but it's still horrible for my website. Has google released any new version of recaptcha or do i need to make any changes for the audio option? -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
