Read the passage below carefully:
Paragraph 1: Across West Africa, indigenous languages face rapid attrition as globalization and urban migration favor major lingua francas. However, contemporary computational linguistics projects are introducing speech-recognition software tuned specifically to unwritten oral dialects, creating digital repositories that systematically document complex phonological structures before they disappear.
Paragraph 2: While early preservation efforts relied on passive audio recordings made by visiting linguists, modern initiatives prioritize community-driven crowdsourcing. Native speakers directly upload oral histories, proverbs, and ecological knowledge into cloud-based platforms, transforming passive subjects into active co-creators of their linguistic heritage.
Paragraph 3: Despite these technological advancements, digital archival efforts confront significant structural hurdles, notably poor broadband infrastructure in rural areas and limited algorithmic datasets for tonal languages. Addressing these technological gaps requires localized offline servers and open-source models trained on diverse regional accents.
Paragraph 4: Ultimately, the survival of endangered languages hinges not merely on digital storage, but on re-integrating archived linguistic assets into local school curricula and civic institutions. Digital archives serve as an essential bridge, providing educational materials that empower communities to revitalize their native tongues in daily public discourse.
Which central argument correctly matches each corresponding paragraph in the passage?
- Paragraph 1Advances in computational linguistics enable the systematic documentation of unwritten indigenous languages threatened by rapid language shift.
- Paragraph 2Community-led digital platforms transform native speakers from passive research subjects into active custodians of oral traditions.
- Paragraph 3Infrastructure deficits and algorithmic limitations present critical obstacles to offline and tonal language archiving.
- Paragraph 4Long-term language revitalization depends on embedding digitally archived materials into formal education and civic life.
