Key Learnings and Their Solutions:
1. Data augmentation: To overcome limited data availability, data augmentation techniques can be employed to generate synthetic data, thereby increasing the size of the training dataset.
2. Transfer learning: Transfer learning allows leveraging pre-trained models on related tasks or languages to bootstrap the development of models for endangered languages, reducing the need for large amounts of labeled data.
3. Active learning: Active learning techniques enable the efficient labeling of data by involving human experts in the iterative training process, focusing on the most informative instances.
4. Unsupervised learning: Unsupervised learning approaches can be utilized to discover patterns and structures in the data without the need for labeled examples, which is particularly beneficial when labeled data is scarce.
5. Dialect adaptation: Developing machine learning models that can handle language variations requires incorporating dialectal data and building models that can adapt to different dialects.
6. Human-in-the-loop: Integrating human-in-the-loop approaches allows for community involvement in the development and evaluation of machine learning models, ensuring cultural sensitivity and accuracy.
7. Collaborations and partnerships: Collaborating with linguistic experts, local communities, and technology organizations can help overcome the challenges of limited funding and technical expertise.
8. Ethical guidelines: Establishing ethical guidelines for language preservation projects involving machine learning is essential to address potential biases, privacy concerns, and cultural sensitivities.
9. User-centered design: Designing machine learning systems with a user-centered approach ensures that the end-users, such as language learners and community members, are actively involved in the development process.
10. Long-term sustainability: Ensuring the long-term sustainability of language preservation efforts requires developing open-source tools, fostering knowledge sharing, and building capacity within local communities.

Related Modern Trends:
1. Multilingual pre-training: Pre-training models on large-scale multilingual corpora can aid in the development of transferable language representations, benefiting endangered languages.
2. Zero-shot learning: Zero-shot learning techniques enable the adaptation of machine learning models to new languages without the need for labeled data, facilitating language revitalization efforts.
3. Neural machine translation: Neural machine translation models can be utilized to bridge the gap between endangered languages and more widely spoken languages, facilitating communication and knowledge exchange.
4. Speech recognition and synthesis: Advances in automatic speech recognition and speech synthesis technologies can assist in documenting and preserving endangered languages by enabling the creation of speech corpora and text-to-speech systems.
5. Mobile applications: Developing mobile applications that incorporate machine learning technologies can facilitate language learning and engagement, making language preservation efforts more accessible.
6. Crowdsourcing: Crowdsourcing platforms can be utilized to involve a larger community in language preservation efforts, enabling the collection of linguistic data and the development of language resources.
7. Natural language processing: Leveraging natural language processing techniques can aid in the analysis and understanding of endangered languages, facilitating language documentation and linguistic research.
8. Virtual reality and augmented reality: Immersive technologies like virtual reality and augmented reality can enhance language learning experiences by providing interactive and engaging environments for language practice and cultural immersion.
9. Social media and online communities: Leveraging social media platforms and online communities can help connect language learners, speakers, and researchers, fostering collaboration and knowledge sharing.
