Reading Transcripts

Parse All Segments

from gemini_caption import GeminiReader

# From file
segments = GeminiReader.read("transcript.md", include_events=True, include_sections=True)

# From string content
segments = GeminiReader.read(markdown_content, include_events=True)

for seg in segments:
    print(f"[{seg.start:.1f}s] {seg.speaker}: {seg.text}")

Extract Dialogue Only

from gemini_caption import GeminiReader

# Returns list of dicts with: text, start, end, speaker, section
dialogue = GeminiReader.extract_dialogue("transcript.md")

for seg in dialogue:
    print(f"{seg['start']:.2f} - {seg['end']:.2f}: {seg['text']}")

GeminiSegment Fields

Each segment has these fields:

  • text: The spoken/event text
  • timestamp: Start time in seconds (or None)
  • end_timestamp: End time in seconds (or None)
  • speaker: Speaker name (e.g., "Mira Murati:")
  • section: Current section title
  • segment_type: "dialogue", "event", or "section_header"
  • line_number: Source line number

Writing Transcripts

Write to File

from gemini_caption import GeminiWriter

segments = [
    {"text": "Welcome everyone.", "start": 0, "end": 2, "speaker": "Host"},

]

GeminiWriter.write_transcript(
    segments,
    "output.md",
    title="My Podcast Episode",
