Interpretation of logo is subjective, this social networking app is about both pic and audio so it was never an intention to related logo with voice.
Regarding the video, all it wants to say is that the orange line is an indicator that the pic can speak.
On my comment, let's go by the merit of the argument rather than getting distracted by our team's aspiration. I repeat "speaking orange line pics" have the best of both pic and video and none of limitations of those 2 media.
