Google Voice is set to launch, marking a significant milestone in telephony innovation after 130 years since the first telephone call. This new service will demonstrate tight integration between web services and traditional phone networks, introducing IVR concepts to a broader customer audience. Google Voice can be integrated with Twilio, allowing users to build their own custom versions of the service using its various features such as inbound/outbound calling, keypad input, call screening, voicemail recording, and speech-to-text transcription. This launch is expected to bring about new opportunities for developers to create innovative communication experiences.
