Quickstart

Get your API key

1. Sign up at console.speechify.ai
2. Go to API Keys
3. Copy your default API key (or create a new one)

Set it as an environment variable so the SDKs pick it up automatically:

$
export SPEECHIFY_API_KEY="your-api-key-here"

Install the SDK

$
pip install speechify-api

Generate speech

Send text to POST /v1/audio/speech. These examples are generated from our Fern SDKs and the API spec, so they switch languages and stay in sync with the live endpoint:

1
curl -X POST https://api.speechify.ai/v1/audio/speech \
2
     -H "Authorization: Bearer <token>" \
3
     -H "Content-Type: application/json" \
4
     -d '{
5
  "input": "Hello! This is the Speechify text-to-speech API.",
6
  "voice_id": "george",
7
  "audio_format": "mp3",
8
  "model": "simba-english"
9
}'

A successful call returns the audio payload:

1
{
2
  "audio_data": "string",
3
  "audio_format": "wav",
4
  "billable_characters_count": 1,
5
  "speech_marks": {
6
    "chunks": [
7
      {
8
        "end": 1,
9
        "end_time": 1.1,
10
        "start": 1,
11
        "start_time": 1.1,
12
        "type": "string",
13
        "value": "string"
14
      }
15
    ],
16
    "end": 1,
17
    "end_time": 1.1,
18
    "start": 1,
19
    "start_time": 1.1,
20
    "type": "string",
21
    "value": "string"
22
  }
23
}

Save and play

Assign the call above to response, then write the audio to output.mp3:

1
with open("output.mp3", "wb") as f:
2
    f.write(response.audio_data)

Then play it from the terminal:

$
afplay output.mp3
