Neapolitan Speech-to-Text: Preserving a Romance Language Through AI

The Language and Where It Is Spoken

Neapolitan (Napulitano) is a Romance language spoken primarily in the Campania region of southern Italy, with significant communities in Basilicata, northern Calabria, and parts of Lazio and Abruzzo. Estimates suggest around 5 to 7 million people speak Neapolitan as a first or second language, though precise figures are difficult due to the lack of official recognition. The language has a rich literary tradition dating back to the 13th century and remains vibrant in music (e.g., Neapolitan songs) and theatre. However, like many regional languages, it faces pressure from Italian, and UNESCO lists it as vulnerable.

Why Accurate Speech-to-Text Matters for Neapolitan

Accurate transcription of Neapolitan is essential for several reasons:

• Documentation: Recording and transcribing oral traditions, folk tales, and dialectal variations helps preserve the language for future generations.
• Accessibility: Neapolitan speakers who are less fluent in Italian can use speech-to-text to interact with digital services in their native tongue.
• Media Production: Podcasters, YouTubers, and filmmakers creating content in Neapolitan can reach wider audiences with subtitles and transcripts.
• Research: Linguists rely on accurate transcripts for phonetic, syntactic, and sociolinguistic analysis.

Specific Transcription Challenges

Neapolitan presents unique obstacles for automatic speech recognition:

Orthographic Variation

There is no universally accepted spelling. Common conventions include:

• The use of apostrophes to mark elision (e.g., 'o for "the" masculine)
• Accents to indicate stress (e.g., é, è)
• Differences in representing the schwa sound (often written as 'e or 'a)

Phonetic Complexity

• Vowel reduction: Unstressed vowels often become schwa or disappear.
• Consonant lenition: Intervocalic /k/, /t/, /p/ become voiced or fricative.
• Gemination: Double consonants are pronounced distinctly (e.g., 'ss' vs 's').

Dialectal Diversity

Neapolitan is not a single variety. The dialect of Naples differs noticeably from that of Salerno or Cilento. An ASR system must be trained on multiple accents to avoid bias.

How Speechyou Handles These Challenges

Speechyou's Neapolitan model is built on a diverse dataset that includes:

• Recordings from multiple dialect areas
• Text corpora with various orthographic styles
• Code-switched speech (Neapolitan-Italian)

The system outputs text in a normalized form that can be edited. Users can choose to export in their preferred orthography by adjusting settings. The acoustic model is fine-tuned to capture the subtle phonetic distinctions, and the language model can handle code-switching seamlessly.

Use Cases in Detail

Oral History Preservation

Elderly Neapolitan speakers often hold unique knowledge of local traditions, cuisine, and folklore. Transcribing their interviews ensures these stories are not lost. Speechyou's real-time transcription allows interviewers to see text as they speak, facilitating note-taking.

Podcast and Video Subtitling

Content creators can upload Neapolitan audio or video and receive SRT or VTT subtitles in minutes. This is particularly valuable for Neapolitan music videos, comedy sketches, and educational content. The subtitles can be further translated into Italian or English to reach a global audience.

Academic Research

Linguists studying Neapolitan morphology or syntax can transcribe field recordings quickly. The high accuracy on clear audio reduces manual correction time, allowing researchers to focus on analysis.

Community Language Learning

Language learners can use speech-to-text to check their pronunciation: they speak a phrase and see if the transcript matches the intended words. This provides immediate feedback.

Conclusion

Neapolitan is a language of immense cultural value, but its future depends on active documentation and use. Speechyou's dedicated speech-to-text solution empowers speakers, researchers, and creators to work with Neapolitan in digital environments. By overcoming the challenges of orthographic variation, phonetic complexity, and dialectal diversity, Speechyou makes Neapolitan transcription accessible to everyone.
