cewsubprocess

This module contains the following classes:

• aeneas.cewsubprocess.CEWSubprocess which is an helper class executes the aeneas.cew C extension in a separate process via subprocess.

This module works around a problem with the eSpeak library, which seems to generate different audio data for the same input parameters/text, when run multiple times in the same process. See the following discussions for details:

class aeneas.cewsubprocess.CEWSubprocess(logger=None, rconf=None)

This helper class executes the aeneas.cew C extension in a separate process by running the aeneas.cewsubprocess.CEWSubprocess.main() function via subprocess.

Parameters:

• rconf (RuntimeConfiguration) – a runtime configuration
• logger (Logger) – the logger object

synthesize_multiple(audio_file_path, c_quit_after, c_backwards, u_text)

Synthesize the text contained in the given fragment list into a wav file.

Parameters:

• audio_file_path (string) – the path to the output audio file
• c_quit_after (float) – stop synthesizing as soon as reaching this many seconds
• c_backwards (bool) – synthesizing from the end of the text file
• u_text (object) – a list of (voice_code, text) tuples

Return type:

tuple (sample_rate, synthesized, intervals)

aeneas.cewsubprocess.main()

Run aeneas.cew, reading input text from file and writing audio and interval data to file.
