# How many Text to Speech requests can I make and can I increase it?

The concurrency limit (concurrent requests running in parallel) depends on the tier you are on.

Below are the current concurrency rates for Text to Speech.

| Plan     | Flash and Turbo models | All other models |
| -------- | ---------------------- | ---------------- |
| Free     | 4                      | 2                |
| Starter  | 6                      | 3                |
| Creator  | 10                     | 5                |
| Pro      | 20                     | 10               |
| Scale    | 30                     | 15               |
| Business | 30                     | 15               |
