to claim

📢 声 voice + 称 to state = to state aloud, i.e. to claim or assert

声 carries the sense of sound or voice and 称 means to call or state. Together they mean putting a claim out loud on the record: to proclaim or assert that something is so.

声 — 士 scholar/warrior on top + 尸-like form + components (simplified from 聲)
声 is the simplified form of 聲, which originally depicted a hanging stone chime (殸) being struck, with 耳 'ear' below to show hearing. The full form combined the sound-making instrument and the act of listening, meaning 'sound' or 'voice'. The modern simplified 声 keeps only the upper portion.

称 — grain 禾 + 尔 (phonetic)
称 is a semantic-phonetic compound: the grain radical 禾 on the left points to weighing grain on a balance, while 尔 hints at the sound. It originally meant 'to weigh' on a steelyard, then extended to 'to state the weight of,' and finally to general senses like 'to call,' 'to name,' or 'title.'
