Why would you yourself use this? Some use cases that might be relevant:
1) Personal notes. Record voice message on your phone and press a button to store online without the friction of dialing a number. Make it trivial to retrieve, organize and share your voice notes online.
2) Group broadcast. Make it faster and easier than group texting, especially for detailed information. Record something e.g., change of plans, post to a URL with one click and broadcast URL to recipients in your contact list.
The latter use case might be really useful for people who don't like to text...granted not your typical HN reader. Think about who might be well served by voice features with SUPER simple user experience.
Also think about non-consumer use cases too...how could companies better disseminate detailed information to employees for example? Which, if any, of these scenarios make more sense with voice features versus simply posting info online?
Solve a real problem first and make customers happy. Then think about how to charge for the value you offer. Have fun, good luck!
