Google Voice is a telecommunications service offered by Google that provides users with a free phone number to make calls, send text messages, and voicemail. It allows users to link the Google Voice number to their mobile phones, tablets, or computers.

Here are some key features of Google Voice:

1. Custom Phone Number: You can choose a unique Google Voice number, which can be used for both personal and business purposes.

2. Call Forwarding: Google Voice allows you to forward calls to multiple devices (like your mobile phone, home phone, or computer), ensuring you never miss a call.

3. Voicemail: Google Voice offers voicemail services with transcriptions, so you can read your voicemails instead of listening to them.

4. Free Texting: You can send and receive text messages through Google Voice, using your Google Voice number.

5. International Calls: Google Voice provides affordable rates for international calling.

6. Integration with Google Services: It integrates with Google’s ecosystem, like Gmail and Google Contacts, making it easy to manage calls and texts alongside other Google services.

Overall, Google Voice is a versatile tool for managing communication, especially for people who want to separate their personal and business calls or need a secondary number.
