It is confirmed that any possible fusion within Alexandrite can talk through Alexandrite. So if for example, Pearl and Amethyst say something together, they'd say it as Opal. We can hear Garnet because Ruby and Sapphire always think as one. They're pretty much used to always being Garnet, and they're still fused with one another. If we apply this logic to Obsidian, then that explains this. That also means that we could hear Ruby and Sapphire talk, as well as all the other possible fusions that could theoretically occur if Ruby or Sapphire fused with any combination of the other Crystal Gems, but since the both of them are always in perfect sync, we hear them as Garnet.
