## 1. Voice overview

In the yellow cloud platform, voice can be configured with quick settings and reusable nodes to ensure that the bot development is much faster and error-free.

There are two methods to configure voice options:

1. [Global options](https://docs.yellow.ai/docs/platform_concepts/studio/tools#25-voice) - Default options for all nodes/journeys.
2. [Node options](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/nodes#32-configure-node-for-a-voice-bot) - Overrides global options for specific nodes wherever it is defined.

**Nodes supported for voice bots**

| Category | Nodes |
| ------------------- | ----------------------------------------- |
| Message and Prompts | [Speak](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/prompt-nodes/#speak), [Name](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/prompt-nodes/#11-name), [Phone Number](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/prompt-nodes/#12-phone), [Question](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/prompt-nodes/#21-question), [Text](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/message-nodes#1-text) |
| Logic | [Condition](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/logic-nodes#1-condition) |
| Action | [Set variables](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/action-nodes#22-variables), [Function](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/action-nodes#24-function), [Database](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/action-nodes#23-database), [API](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/action-nodes#21-api), [Execute Flow](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/action-nodes#15-execute-flow) |

In this section you will learn:
1. How a voice bot flow works and how to get started.
2. Few use-cases on how to make use of the voice functionalities, like delays, recording and forwarding options, DTMF and configuring STT and TTS engines.
