If Kenku can’t speak, does that mean no spells with verbal components?

@JeremyECrawford if kenku can't speak, does that mean no spells with verbal components (i.e. almost all of them)? Mimicry sufficient?

Kenku speak by mimicking sounds they've heard. They're not prevented from uttering verbal components. #DnD https://t.co/Je0vy1Kai1
