👉 Weak sounds, also known as fricatives or nasals at the beginning of words, are often produced by constricting airflow through a narrow passage in the mouth and can include sounds like "f," "p," "b," "m," and "n" depending on how it is articulated. These sounds are typically softer than plosives (like "p" and "b"), creating a hissing or whisper-like quality, especially when air leaks around the edges of the articulators.
