In this tutorial we will describe how to use the **prosody functions in the TTS editor for announcements created on the TTS library tab when you for example want to add or modify some static text.** All of the **prosody features** in the TTS editor **are for adjusting and fine-tuning the audio translation** of the announcement; you know most of them from Microsoft Azure. If you don't edit the translation or pronunciation, TTS Voice will read everything as is, and, except in English, it may not sound right. **The *pronunciation* of words may not be sufficient for some languages** **and more fine-tuning could be required using other prosody features**. You may want also adjust the *intonation* in certain cases or increase or decrease the speed of particular announcement segments, insert pauses etc. **Each prosody feature** is represented in the TTS Editor by a **different color**. When you apply these features to selected text that is part of an audio translation, the **text is underlined with the color corresponding to the applied feature**. In contrast, the **breaks** (pauses) and **structure editor functions** are displayed as **bubbles of a specific color**. **Note**: The announcements you see here are used in GateUI and BaggageUI.

However, you can copy the non existing phonemes from English to Spanish.
