# [SSFM only] Predefined style of speaking

All SSFM-based actors come with 4 basic emotions by default: `normal`, `happy`, `sad`, and `angry`. You can adjust the intensity of these emotions to achieve the exact mood you want. These presets make it easy to add natural-sounding emotions to your text-to-speech output.

Follow the steps below:

### Step 1. Check Available Actors

```bash
curl \
    --request GET \
    --url https://typecast.ai/api/actor/ \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer $API_TOKEN"
```

### Step 2. Check if the Actor Supports SSFM

Using the `actor_id` from Step 1, call the following API. If the `display_name` starts with `SSFM-`, it means the actor supports the SSFM model. Use the `name` value from this result in Step 3.

```bash
curl \
    --request GET \
    --url https://typecast.ai/api/actor/${24-letters-your_actor_id}/versions \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer $API_TOKEN"
```

### Step 3. Request Speech Generation

Use the SSFM `name` obtained in Step 2 as the `model_version` in your speech generation request. It will usually be something like `v1`, `v2`, etc. Set `emotion_tone_preset` to `normal-1`, and choose one of `happy`, `sad`, or `angry` for `emotion_label`. The default value for `emotion_scale` is 1.0, but you can increase it up to 2.0 for a stronger emotional effect.

```bash
curl \
  --request POST \
  --url https://typecast.ai/api/speak \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer $API_TOKEN" \
  --data '{
    "text": "My name is Typecast.",
    "lang": "auto",
    "xapi_hd": true,
    "actor_id": "6059dad0b83880769a50502f",
    "model_version": "v5",
    "emotion_tone_preset": "normal-1",
    "emotion_label": "angry",
    "emotion_scale": 1
}'
```
