icespeak 0.3.3

Icespeak - Icelandic TTS library

Icespeak

Icespeak is a Python 3.9+ library that makes Icelandic-language speech synthesis easy.

Local installation

Note: The Azure TTS package currently only supports the very out-dated OpenSSL version 1.*

Clone the repository and cd into the folder. Then create and activate a virtual environment:

python3 -m venv venv
source venv/bin/activate

Install minimal set of dependencies to use the library:

python3 -m pip install .

Alternatively, to install in editable mode with extra dev dependencies:

python3 -m pip install -e '.[dev]'

Usage

Before using, place API keys for the relevant services in the /keys folder (or a folder specified by the ICESPEAK_KEYS_DIR environment variable).

Output audio files are saved to the directory specified by the ICESPEAK_AUDIO_DIR environment variable. By default Icespeak creates the directory <TEMP DIR>/icespeak where <TEMP DIR> is the temporary directory on your platform, fetched via tempfile.gettempdir().

By default, generated audio files are removed upon a clean exit, but this can be disabled by setting ICESPEAK_AUDIO_CACHE_CLEAN=0.

Text-to-speech

Simple example of TTS, which includes phonetic transcription:

from icespeak import tts_to_file, TTSOptions
text = """\
Þetta er texti fyrir talgervingu. \
Í honum er ýmislegt sem mætti vera hljóðritað, \
t.d. ræður talgerving oft illa við íslenskar skammstafanir, \
tölvupósta eins og [e-mail],
eða prósentur eins og 48,3%, o.fl.\
"""
tts_out = tts_to_file(
    text,
    TTSOptions(
        text_format="text", # Set to 'ssml' if SSML tags in text should be interpreted
        audio_format="mp3", # Output audio will be in mp3 format
        voice="Gudrun" # Azure TTS voice
    ),
    transcribe=True # Default is True
)
print(tts_out.file) # pathlib.Path instance pointing to file on local file system
print(tts_out.text) # text that was sent to the TTS service (after the phonetic transcription)

Results are cached, so subsequent calls with the same arguments should be fast.
