Yes, getting a voice teacher is both the fastest and healthiest way to go about this. While there are plenty of resources available online and there are countless self-taught singers it's easy to acquire unhealthy habits, which in turn might also limit your progress and ability over time. Latency can be a problem with anything music-related in an online setting, though. Apart from that, singing is very much a physical activity and some feedback from your body might be missed due to limitations of the medium. Nevertheless, it certainly is a viable and tested approach (with many teachers and even well-known singers offering personal training online) and worth a try.
