META introduces Voicebox: The first Generative AI to generalize across tasks with top performance

Meta has unveiled Voicebox, a groundbreaking generative AI model redefining speech synthesis. Trained on a vast dataset of 50,000+ hours of unfiltered audio, Voicebox seamlessly performs tasks such as editing, noise removal, and style transfer without task-specific training. Its non-autoregressive flow-matching model infills speech based on contextual cues, generating high-quality audio clips in multiple languages.

Voicebox achieves speech recognition performance on par with real speech, with just a 1% error rate degradation. Its zero-shot text-to-speech training method, Flow Matching, outperforms existing models in intelligibility and audio similarity while operating up to 20 times faster. Voicebox revolutionizes speech synthesis, empowering virtual assistants, gaming NPCs, and assisting individuals with vocal cord damage.

^{PYTHON TIP}
Empty List

A straightforward way to check if a list is empty in Python is to take advantage of Python's ability to interpret empty collections (like lists) as “False” in a boolean context, as shown in the code snippet below.

In provided example, an empty list will be evaluated as “False", so “not x” will be “True” if the list “x” is empty. This is a clean and efficient way to check for an empty list and is considered a good practice in Python.

Note that this will also work with other collections (like tuples, sets, and dictionaries) and strings, because Python treats empty collections and strings as “False” when converting them to a boolean context.

x = []
if not x:
print("List is empty")


# Output: List is empty
