# Create personalized voice messages from a spreadsheet

**Use case:** 

Upload a customer list and turn one message template into a personal MP3 voice note for every row, such as order updates, reminders or welcome messages. Placeholders like {{First name}} and {{Order}} are filled in per row, each file is named after its order number, and every clip comes with timed subtitles.

## Input

```json
{
  "texts": [
    "Hi {{First name}}, good news: your order {{Order}} is on its way to {{City}} and should arrive on {{Delivery day}}. Thanks for shopping with us!"
  ],
  "spreadsheetFile": "https://api.apify.com/v2/key-value-stores/I40EWpLzQaVq08gCm/records/customer-orders-sample.csv",
  "fileNameColumn": "Order",

  "generateSubtitles": true,
  "subtitleGranularity": "sentence",
  "subtitleFormat": "srt",
  "combineAudio": false,
  "maxConcurrency": 5,
  "listVoices": false
}
```

## About this Actor

This example demonstrates how to use [Bulk Text to Speech: MP3 + SRT Subtitles | No API Key](https://apify.com/fayoussef/bulk-text-to-speech.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/fayoussef/bulk-text-to-speech.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/fayoussef/bulk-text-to-speech.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
