:bulb: Complete details on designing a voice bot conversation using the conversation design module are explained [here](https://docs.yellow.ai/docs/platform_concepts/design/convdesignvoice).
:::

In this article, you will understand how to design a conversation with help of an example.

**Example use case to build a voice bot**

Let us consider a use case to build a *Banking voice bot* that asks a set of questions to identify the user and provide a resolution for the asked queries (as shown in the below conversation). This is a happy conversation flow where the bank account holder provides his name and phone number and asks for the eligible home loan and the bot replies with the details.


Let's break down the conversation:

* **Bot** (asks): What is your name?
* **User**(replies): Karan
* **Bot**(stores): Karan as Name
* **Bot** (asks): How may I help?
* **User**(replies): Loan eligibility
* **Bot**(understands): User request = Loan eligibility
* **Bot**(logic): Required phone number to calculate Loan eligibility
* **Bot** (asks): What is your phone number?
* **User**(replies): 9890******
* **Bot**(validates if the number is correct): Uses logic to calculate Loan eligibility
* **Bot** (response): You can avail X amount on X% interest.

To build this,

1. Open **Conversation design**.

> This will work as a voice conversation designer only if you had selected the Type as Voice while creating a bot).

:::note
Bot persona is already configured with the default settings. To customize further, click **Settings** and select the required options.

:::

2. Create a dialogue for the initial conversation:
- Add initial conversation, fetch user details (Example: Name)
- Ask the determining question to fetch the response from the user(example: Response).
- The answer fetched will be the intent based on which the next flows will be executed.


3. Determine the **Intent** (next action) based on the user input using a condition.
- If the user response is identified as Loan eligibility, execute **Loan eligibility** flow.
- If the response is to create a new bank account, execute the **Crete account** flow. So on...


4. Create the next flows based on the obtained information. That is- loan eligibility flow.
- Two dialogues are used in this because, after obtaining the phone number a logical action must be performed where the number is verified on the database and the loan details are obtained. This can be added on **Studio**.


5. **SSML Settings**:

- Configure fallbacks that are spoken out when the user responds with an unexpected message.


- Add node-level settings like emphasis, interpret, pause, and music.


6. You can [preview](https://docs.yellow.ai/docs/platform_concepts/design/convdesignvoice) the design by connecting your bot to the IVR number and requesting a call.

7. Switch to **Studio**. Flows are in sync with the design module.
- Text entered in the dialogue boxes are segregated and converted to Voice inpute nodes with SSML configurations.
- You can edit the flows further. For example, open the **Loan eligibility** flow, add database and function to calculate the loan and interest rate.


8. Publish the changes. Once approved, the voice bot will go live and can receive customer calls.
