I think voice is a visionary concept to make Thisbe world truly decentralised and steem is showing the support by listing eos on steem-engine . So we should support voice not as competition but as friendly platform to grow and earn some money. I think after launch of voice and its native token it will be listed on steem-engine.
we all should join that platform and advertise about steemit platform so that it will be win-win situation for that platforms.
