aflr is the official api.audio Python 3 SDK. This SDK provides easy access to the api.audio API from applications written in python.
This repository is actively maintained by Aflorithmic Labs. For examples, recipes and api reference see the api.audio docs.
You don't need this source code unless you want to modify it. If you want to use the package, just run:
pip install aflr -U
Install from source with:
python setup.py install
Python 3.6+
Create a file hello.py
touch hello.py
The library needs to be configured with your account's secret key which is available in your Aflorithmic Dashboard. Import the aflr package and set aflr.api_key with the api-key you got from the dashboard:
import aflr
aflr.api_key = "your-key"
Let's create our first audio from text.
✍️ Create a new script:
script = aflr.Script.create(scriptText="Hello world", scriptName="hello")
print(script)
🎤 Create an speech audio file from the script using Joanna's voice:
response = aflr.Speech.create(scriptId=script["scriptId"], voice="Joanna")
print(response)
🎧 Now let's master the speech file with high quality and a nice background track.
response = aflr.Mastering.create(
scriptId=script.get("scriptId"),
backgroundTrackId="full__citynights.wav"
)
print(response)
🎉 Finally, get the urls of the audio files generated:
urls = aflr.Mastering.retrieve(scriptId=script["scriptId"])
print(urls)
Or download the files in your current folder:
filepath = aflr.Mastering.download(scriptId=script["scriptId"], destination=".")
print(filepath)
Easy right? 🔮 This is the hello.py final picture:
import aflr
aflr.api_key = "your-key"
# script creation
script = aflr.Script.create(scriptText="Hello world", scriptName="hello")
# speech creation
response = aflr.Speech.create(scriptId=script["scriptId"], voice="Joanna")
print(response)
# mastering process
response = aflr.Mastering.create(
scriptId=script.get("scriptId"),
backgroundTrackId="full__citynights.wav"
)
print(response)
# get url of audio tracks generated
urls = aflr.Mastering.retrieve(scriptId=script["scriptId"])
print(urls)
# or download
filepath = aflr.Mastering.download(scriptId=script["scriptId"], destination=".")
print(filepath)
Now let's run the code:
python hello.py
Once completed, check the files in the hello.py root folder - you will see a new audio file. Play it!
import aflr
The library needs to be configured with your account's secret key which is available in your Aflorithmic Dashboard. Set aflr.api_key with the api-key you got from the dashboard:
aflr.api_key = "your-key"
You can also authenticate using aflr_key environment variable and the aflr SDK will automatically use it. To setup, open the terminal and type:
export aflr_key=<your-key>
If you provide both environment variable and aflr.api_key authentication, the aflr.api_key will be used.
There are two approaches to use the resources.
First approach is to import the resource classes you want to use first, then use resource methods. For example, to use Script, we could do:
from aflr import Script
Script.create()
The second approach is to use it directly from aflr:
import aflr
aflr.Script.create()
Same logic applies for other resources (Speech, Voice, Sound...)
Script resource The Script resource/class allows you to create, retrieve and list scripts. Learn more about scripts here.
Script methods are:
create() - Create a new script.
scriptText * [Required] (string) - Text for your script. A script can contain multiple sections and SSML tags. Learn more about scriptText details hereprojectName (string) - The name of your project. Default value is "default"moduleName (string) - The name of your module. Default value is "default"scriptName (string) - The name of your script. Default value is "default"scriptId (string) - Custom identifier for your script. If scriptId parameter is used, then projectName, moduleName and scriptName are required parameters.script = aflr.Script.create(
scriptText="<<sectionName::hello>> Hello {{username|buddy}} <<sectionName::bye>> Good bye from {{location|barcelona}}",
projectName="myProject",
moduleName="myModule",
scriptName="myScript",
scriptId="id-1234"
)
retrieve() - Retrieve a script by id.
scriptId * [Required] (string) - The script ID you want to retrieve.script = aflr.Script.retrieve(scriptId="id-1234")
list() - List all scripts available in your organization.
scripts = aflr.Script.list()
get_random_text() - Retrieve random text from a list of categories.
category (string) - The category from which the random text is retrieved. If no category is specified, the function defaults to "FunFact"text = aflr.Script.get_random_text(category="BibleVerse")
"BibleVerse", "FunFact", "InspirationalQuote", "Joke", "MovieSynopsis", "Poem", "PhilosophicalQuestion", "Recipe", "TriviaQuestion".Speech resource Speech allows you to do Text-To-Speech (TTS) with our API using all the voices available. Use it to create a speech audio file from your script.
Speech methods are:
create() Send a Text-To-Speech request to our Text-To-Speech service.
scriptId * [Required] (string) - The script IDvoice (string) - Voice name. See the list of available voices using Voice resource. Default voice is "Joanna".speed (string) - Voice speed. Default speed is 100.effect (string) - Put a funny effect in your voice. You can try the following ones: dark_father, chewie, 88b, 2r2d, volume_boost_low volume_boost_middle volume_boost_high (Volume boost allows you to adjust the volume of speech. NOTE! Volume boost effect only applies to speech creation and will be overwritten by the mastering process)silence_padding (integer) - Add a silence padding to your speech tracks (in milliseconds). Default is 0 (no padding)audience (dictionary) - List of dicts containing the personalisation parameters as key-value pairs. This parameter depends on the number of parameters you used in your script resource. For instance, if in the script resource you have scriptText="Hello {{name}} {{lastname}}", the audience should be: [{"username": "Elon", "lastname": "Musk"}]sections (dictionary) is a dictionary (key-value pairs), where the key is a section name, and the value is another dictionary with the section configuration ( valid parameters are: voice, speed, effect, silence_padding). If a section is not found here, the section will automatically inherit the voice, speed, effect and silence_padding values you defined above (or the default ones if you don't provide them). See an example below with 2 sections and different configuration parameters being used.
sections={
"firstsection": {
"voice": "Matthew",
"speed": 110,
"silence_padding": 100,
"effect": "dark_father"
},
"anothersection": {
"voice": "en-GB-RyanNeural",
"speed": 100
}
}
voiceName (DEPRECATED, use voice instead)scriptSpeed(DEPRECATED, use speed instead)response = aflr.Speech.create(
scriptId="id-1234",
voice="Joanna"
)
response = aflr.Speech.create(
scriptId="id-1234",
voice="Matthew",
