Welcome Speech is an Android app developed by Pratik Nandha that allows you to customize the greetings spoken by your phone. Whether it's when your phone starts up, shuts down, or when you unlock it, you can set a personalized message that will be spoken out loud by the app.

With Welcome Speech, you can choose any text you want your phone to say, making it a fun and unique way to personalize your device. Additionally, the app has specific greetings for different times of the day. For example, between 7 AM and 8 AM, it will say "Good Morning," between 12 PM and 1 PM, it will say "Good Noon," and between 11 PM and 12 AM, it will say "Good Night."

The app also offers the option to stop the service if you no longer want the greetings to be spoken, and it can even be set to play in silent mode. Furthermore, you can customize how you want to be addressed, whether as "Sir" or "Madam."

Welcome Speech provides several features to enhance your phone's greetings experience. When your phone starts up, it will say "System started, Sir/Madam," and when it shuts down, it will say "System shutting down, Sir/Madam." Additionally, when you open the app for the first time, it will say "Welcome, Sir/Madam," and thereafter, it will say "Welcome back, Sir/Madam."

To ensure the app functions properly, make sure to check the accessibility settings and test your default voice. If needed, you can download a Text-to-speech synthesis engine from the Play Store. Overall, Welcome Speech is a convenient app that adds a personal touch to your phone's greetings.
