Phonetician / Linguist (Spanish-US)

Role Purpose Ensure the linguistic and phonetic quality of Omilia’s multilingual Text-to-Speech (TTS) systems by designing phoneme inventories, developing lexicons, and reviewing audio corpora to support enterprise-grade voice experiences. Accountabilities Autonomy: Independently conduct phonological and phonetic analysis, design phoneme inventories, and develop lexicons for multiple languages. Scope & Complexity: Responsible for linguistic quality across all supported languages in TTS, including handling underrepresented phenomena and complex language-specific features. Impact: Directly influences the naturalness, accuracy, and quality of Omilia’s TTS output, impacting customer experience in global contact center deployments. Influence/Mentorship: Collaborates with TTS engineers, data scientists, and ML researchers; coordinates with native-speaker reviewers and external annotation pipelines. Key Responsibilities Conduct systematic phonological and phonetic analysis of the American Spanish language. Document language-specific features (prosody, stress, tone, coarticulation, dialect variation). Produce structured language profiles for TTS model training and evaluation. Define and maintain phoneme inventories; map to IPA and TTS-specific conventions. Corpus audits and optimal audio references selections for TTS target voice tuning. Build and maintain pronunciation lexicons, including G2P rules and exceptions. Review and correct machine-generated G2P outputs; conduct pronunciation audits. Annotate audio corpora, develop evaluation protocols, and produce error analyses. Define linguistic criteria for TTS corpus selection and design prompts for data collection. Collaborate with TTS engineers to integrate linguistic artefacts into synthesis pipelines. Contribute to internal documentation and participate in research discussions. #J-18808-Ljbffr Omilia - Conversational Intelligence
