FAQ
Q: What is included in the Mazanderani Speech Dataset?
A: The Mazanderani Speech Dataset features 108 hours of professionally recorded audio from native Mazanderani speakers across Mazandaran province along Iran’s Caspian coast. The collection comprises 748 annotated files in MP3/WAV format totaling approximately 183 MB, complete with transcriptions, speaker demographics, regional information, and linguistic annotations.
Q: How does Mazanderani differ from Persian?
A: Mazanderani is a Northwestern Iranian language distinct from Persian with unique phonology, grammar, and vocabulary. The dataset includes detailed linguistic annotations marking Mazanderani-specific features, ensuring trained models recognize it as separate language rather than Persian dialect. This respects Mazanderani linguistic identity in northern Iran’s Caspian regions.
Q: What makes Mazanderani culturally significant?
A: Mazandaran has distinctive culture shaped by Caspian coastal geography including unique music traditions, cuisine, and social practices. Mazanderani language embodies this cultural identity. The dataset supports preservation of Mazanderani culture through voice technology, maintaining linguistic heritage in one of Iran’s most geographically distinctive regions.
Q: Can this dataset support tourism applications?
A: Yes, Mazandaran is popular tourist destination for Iranians seeking Caspian coast and forest tourism. The dataset supports development of voice-guided tours, tourism information systems, and hospitality applications in Mazanderani, enhancing visitor experiences while promoting regional language and supporting local tourism industry.
Q: What regional variations are represented?
A: The dataset captures Mazanderani speakers from across Mazandaran province representing coastal and inland varieties. With 748 recordings from diverse speakers, it ensures comprehensive coverage of Mazanderani as spoken across different areas of the province along Caspian coast and Alborz mountain foothills.
Q: How diverse is the speaker demographic?
A: The dataset features 46% female and 54% male speakers with age distribution of 30% aged 18-30, 21% aged 31-40, 23% aged 40-50, and 26% aged 50+. This ensures models perform well across different demographic groups in Mazandaran.
Q: What applications are suitable for Mazanderani technology?
A: Applications include tourism information systems for Caspian region, cultural heritage documentation, regional media transcription, local government multilingual services, agricultural advisory for rice cultivation and forestry, educational tools for Mazanderani language learning, and community platforms serving northern Iran’s Caspian communities.
Q: Why is language preservation important for Mazanderani?
A: Mazanderani faces pressure from Persian as dominant language and younger generations increasingly using Persian. Technology applications in Mazanderani help maintain language vitality, make it relevant for digital age, support intergenerational transmission, and ensure Mazanderani remains living language rather than becoming heritage language.
How to Use the Speech Dataset
Step 1: Dataset Acquisition
Download the dataset package from the provided link. Upon purchase, you will receive access credentials and download instructions via email. The dataset is delivered as a compressed archive file containing all audio files, transcriptions, and metadata.
Step 2: Extract and Organize
Extract the downloaded archive to your local storage or cloud environment. The dataset follows a structured folder organization with separate directories for audio files, transcriptions, metadata, and documentation. Review the README file for detailed information about file structure and naming conventions.
