Yep, telecommunication sounds right. I wish we'd get some sort of pyramid article giving actual guidelines for telecommunication that's not one of the basic types given. It doesn't come up much, but when it does, you really want it.

I don't know if 5 or 10 is the right amount for this telecommunication. Its not secure, and its quite close range. It does stick around, which is worth something. I lean towards 5 rather than 10. Still if you ever need to modify it, it gets sticky: cross-world pheromone communication is quite cheap with this build.

I don't think simply adding to mute to a creature who can pheromone but not speak in any case where the campaign isn't very human-centric. Though I suppose the voice synthesizer is reasonably appropriate. Ultra tech does funny things to trait values.
