Python script that lets you easily convert text to synthesized audio files, with help of Amazon's IVONA.

Project description

Build Status PyPI Version Python Versions License

Python (3) script that lets you easily convert passed text to synthesized audio files, with help of Amazon’s IVONA. All you need is a pair of keys and this script. Yes, that’s literally everything you need to never speak again. If that’s your thing of course.

If you want to use IVONA Speech Cloud directly inside your (probably awesome) Python project then have a look at python-ivona-api, which this script also uses.

Installation

With pip (recommended):

$ pip3 install ivona_speak

Without pip:

$ git clone https://github.com/Pythonity/ivona-speak
$ pip install -r ivona-speak/requirements.txt
$ cd icon-font-to-png/bin

Usage

The script comes with two subcommands (synthesize is the default one):

$ ivona-speak synthesize -h
Usage: ivona-speak synthesize [OPTIONS] TEXT

  Synthesize passed text and save it as an audio file

Options:
  --access-key TEXT          IVONA Speech Cloud access key.
  --secret-key TEXT          IVONA Speech Cloud secret key.
  -a, --auth-file FILENAME   Path to YAML file with 'access-key' and 'secret-
                             key' set.
  -o, --output-file PATH     Output audio file path.  [required]
  -n, --voice-name TEXT      Voice name (default: Salli).
  -l, --voice-language TEXT  Voice language (default: en-US).
  -c, --codec [ogg|mp3|mp4]  Used codec (default: mp3).
  -h, --help                 Show this message and exit.
$ ivona-speak list-voices -h
Usage: ivona-speak list-voices [OPTIONS]

  List available Ivona voices

Options:
  --access-key TEXT          IVONA Speech Cloud access key.
  --secret-key TEXT          IVONA Speech Cloud secret key.
  -a, --auth-file FILENAME   Path to YAML file with 'access-key' and 'secret-
                             key' set.
  -l, --voice-language TEXT  Filter voice by language.
  -h, --help                 Show this message and exit.

Examples

With above usage everything should be pretty clear, but in case it isn’t:

You can provide keys either explicitly or put them in YAML file (one of those ways is required):

$ ivona-speak list-voices --access-key 'YOUR_ACTUAL_ACCESS_KEY' --secret-key 'YOUR_ACTUAL_SECRET_KEY'
$ ivona-speak list-voices -a secrets.yaml

Also, synthesized is the default subcommand so those do the same:

$ ivona-speak synthesize -a secrets.yaml -o hello_world.mp3 'Hello world!'
$ ivona-speak -a secrets.yaml -o hello_world.mp3 'Hello world!'

List all available IVONA voices, and list them now:

$ ivona-speak list-voices -a secrets.yaml

I want someone to say ‘Hello world!’, and say it quick:

$ ivona-speak synthesize -a secrets.yaml -o hello_world.mp3 'Hello world!'

She sounds so nice. I want someone special to respond her:

$ ivona-speak synthesize -a secrets.yaml -o response.mp3 -n Joey 'How you doin?'

Example auth file

$ cat secrets.yaml
access-key: YOUR_ACTUAL_ACCESS_KEY
secret-key: YOUR_ACTUAL_SECRET_KEY

Tests

Package was tested with pytest and tox on Python 3.4 (see tox.ini).

To run tests yourself you need to set environment variables with secret and access keys before running tox inside the repository:

export IVONA_ACCESS_KEY="YOUR_ACTUAL_ACCESS_KEY"
export IVONA_SECRET_KEY="YOUR_ACTUAL_SECRET_KEY"
