In `@docs/5`. Integrations/Speech-to-text and Text-to-speech in Glific.md:
- Line 6: Replace the outdated "Last Updated: April 2025" metadata in the table
cell that currently reads "<td style={{ paddingLeft: 40 }}><b>Last Updated:
April 2025</b></td>" with the correct 2026 date (e.g., "<b>Last Updated: April
14, 2026</b>" or "<b>Last Updated: April 2026</b>") so the document reflects the
PR creation date and the January 2026 provider change.
- Line 13: The sentence about providers is ambiguous and grammatically broken;
update the sentence that mentions "Bhashini" and "Gemini 2.5 pro" so it clearly
states that webhook names still reference the legacy provider "Bhashini" while
the actual backend has been switched to Google's Gemini 2.5 Pro since January
2026 (e.g., replace the current sentence with a concise line like: webhook names
remain "Bhashini" for legacy reasons, but the active speech-to-text and
text-to-speech backend has been Google Gemini 2.5 Pro since January 2026).
- Line 133: The sentence "Apart from Gemini, OpenAI can also be used as the
speech engine for engine can also be used to generate text-to-speech (TTS)
responses." contains a duplicated phrase; edit the sentence containing "speech
engine for engine" (the OpenAI TTS description) to remove the duplication and
make it read smoothly, e.g., "Apart from Gemini, OpenAI can also be used as the
speech engine to generate text-to-speech (TTS) responses," ensuring the rest of
the paragraph remains grammatically consistent.
