Basic text normalization using English normalizer

from nemo_text_processing.text_normalization.normalize import Normalizer normalizer = Normalizer(input_case='cased', lang='en') text = "He was born on Dec 3rd, 1978." normalized = normalizer.normalize(text, verbose=True) print(normalized) # Output: "He was born on December third, nineteen seventy eight."

Known issues
gotchaThe normalizer expects input_case='cased' or 'lower_cased'; using default may produce unexpected results for certain texts.
fix
Explicitly set input_case parameter.

breakingIn v1.0.0, the get_normalizer function moved from nemo_text_processing.text_normalization to nemo_text_processing.utils.
fix
Update import to from nemo_text_processing.utils import get_normalizer

gotchaNormalization depends on pynini (WFST library). Installation issues on Windows or Python 3.12+ may cause runtime errors. For Windows, consider installing pynini from conda-forge.
fix
Use conda install -c conda-forge pynini on Windows, or use a Linux environment.
