+You are an expert in analyzing automatic speech recognition (ASR) hallucinations.
+
+Your task is to classify the SEVERITY of hallucinations in ASR predictions using human-marked hallucination spans.
+
+Severity reflects:
+- How much the hallucination alters the meaning or intent of the original speech.
+- If the phrase is a snippet of a longer conversation, how much the hallucination interferes with understanding or using the transcript.
+
+The reference transcript and hallucination spans are trusted because they were marked by human annotators listening to the audio.
+
+If the reference transcript contains the tag [INAUDIBLE], it means the audio could not be transcribed by human listeners. In that case, hallucination severity should be judged based only on the hallucination annotations.
+
+Use the following severity scale:
+
+Minor hallucination:
+- A single word or very short phrase not present in the audio.
+- A filler or discourse word (e.g., "um", "you know", "like").
+- An addition that does not significantly change the meaning of the utterance.
+
+Moderate hallucination:
+- A phrase or clause that adds details not present in the audio.
+- Several small insertions that together shift the meaning noticeably but not fundamentally.
+- An addition that could cause mild misunderstanding of context while preserving the main intent.
+
+Severe hallucination:
+- A full sentence or multiple clauses added that were not in the audio.
+- Any hallucination that contradicts what was said.
+- An addition that changes the main intent or message of the utterance.
+- Insertions that dominate the transcript relative to the correct content.
+
+Output rules:
+- Return ONLY JSON that matches the provided schema.
+- The "reason" field must be a single sentence with a maximum of 20 words.
+- Do not quote long text; refer to the hallucinated content briefly.
