Tip Refer to the **DTMF** node [article](/v1/docs/flow-builder-dtmf) for information about how to use the **DTMF** node together with the **Play Audio** node. Two types of announcements are supported: - [Media](/v1/docs/administration-media) (Voice) message - [Text-to-speech](/v1/docs/text-to-speech) message ### Connections The **Play Audio** node supports unlimited input connections and 1 output connection. ## Using the Play Audio node To add a **Play Audio** node to your interaction flow, click the **Play Audio node** icon: ![Flow Builder Play Audio Node](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Flow%20Builder%20Play%20Audio%20Node.png) The **Play Audio** node allows multiple input connections and a single output connection. To make an input connection, drag a link from any node supporting an output connection to the **Play Audio** node. To make an output connection, drag a link from the **Play Audio** node to any node supporting an input connection. ![Flow Builder Play Audio Node Making Links](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Flow%20Builder%20Play%20Audio%20Node%20Making%20Links.gif) Tip In the **DTMF** node, specify an [audio message file](/v1/docs/flow-builder-dtmf#audio-file) that describes the key selections available in the **DTMF** node so that contacts can make a key selection without having to listen to the entire audio message first. ## Configuring the Play Audio node To configure a **Play Audio** node in your interaction flow, click the **Play Audio** node to display the **Play Audio** panel. In the **Play Audio** panel, click the "i" icons to read information about the configuration menus and fields. ![Flow Builder Play Audio Node Configuration Panel](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Flow%20Builder%20Play%20Audio%20Node%20Configuration%20Panel.png) In the **Method** section, choose from one of two audio message types, **Media** or **Text-to-speech**. The [Media](/v1/docs/administration-media) type plays an audio file of type *Voice message* while the [Text-to-speech](/v1/docs/text-to-speech) type plays a text message as spoken audio using one of the [supported voices](/v1/docs/voice-samples). ### Rename the node Beginning with the [September 15 - 19, 2025 release](/v1/docs/september-15-19-2025), you may name nodes in **Flow Builder**. Click a node in the node palette to add it to the flow. The node is added to the flow and is named **Node N**, where **N** represents the number of the node; for example, **Node 6**. Below the node name is the node type, such as **Play Audio**. Click the node to open the node configuration panel, then click the name of the node to edit it. Enter a new name, then the check mark to save your change.

Use the **Audio file** menu to select a voice message from your [media library](/v1/docs/administration-media). ![Flow Builder Play Audio Node Configuration Panel Media Option](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Flow%20Builder%20Play%20Audio%20Node%20Configuration%20Panel%20Media%20Option.png) ### Text-to-speech To play a spoken announcement from a text message when the interaction arrives at the **Play Audio** node in the interaction flow, select **Text-to-speech** in the **Method** section. Use Text-to-Speech as a virtual agent or receptionist to optimize inbound call flow efficiency. This versatile tool can handle multiple self-service tasks, such as checking and reporting on order statuses, account balances, opening hours, booking information, and appointment scheduling. Text-to-Speech supports 20 languages, offering both male and female voices for many of them. You can also customize the standard voices using the extensive expression options available with Speech Synthesis Markup Language (SSML) to create nuanced announcements. System and custom variables are also supported, enabling you to personalize messages. Text-to-Speech delivers a real-time virtual agent experience with responses in under one second, even for large scripts. ![Flow Builder Play Audio Node Configuration Panel TTS Option](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Flow%20Builder%20Play%20Audio%20Node%20Configuration%20Panel%20TTS%20Option.png) Click **Play** to preview the message. Click **Download** to save a copy of the message as an MP3 file on your device. #### Language Choose one of the supported langauges from the **Language** menu. Refer to [Language support](/v1/docs/tts-overview#language-support) for a list of current language support. ![Flow Builder Play Audio Node Configuration Panel TTS Spanish Option](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Flow%20Builder%20Play%20Audio%20Node%20Configuration%20Panel%20TTS%20Spanish%20Option.png) #### Voice Different voices are available depending on which language you choose. Some languages have multiple voices and genders for you to choose from, while others currently only have a single voice. Select the voice you want to use to synthesize your text message into spoken audio. Refer to [Voice samples](/v1/docs/voice-samples) to play audio clips of the different voices to help you select the voice that is best for your business. Tip You can use the `<lang>` SSML tag to have text of one language spoken in the voice of a different language. #### Message Enter the message that the **Play Audio** node will convert into synthesized speech and play to your contacts. If you enter plain text, the message is spoken in the selected language and voice with the default inflection. To enhance the way the voice sounds, use Speech Synthesis Markup Language ([SSML](/v1/docs/ssml-syntax)) to add more personality and character to your voice messages. Use [system and custom variables](/v1/docs/flow-builder-variable-management) to personalize messages with content such as the caller's name, a confirmation number, or other information retrieved by the flow using nodes such as **[HTTP Request](/v1/docs/http-request)** and **[DTMF](/v1/docs/flow-builder-dtmf)**. The way a call or other interaction is routed within your contact center system from IVR to queue to agent or voicemail. An ideal flow always enables an interaction to reach the best target to handle it. A well designed flow never lets the caller reach a deadend or loop. A flow is your customer service road map. A well designed flow ensures that callers are given the correct options for the time of day they call. A good flow ensures that the call reaches resolution in the most efficient way. ## Related - [Flow Builder Overview](/inbound-flow-builder-overview.md) - [Flows](/inbound-flows.md)
