Insight for: Indicate stress in words

This issue, similar to 4208860541, underscores a persistent challenge in OmniVoice's 'Russian' language support: the inconsistent ability to 'indicate primary stress in words.' The observation that 'capitalizing the stressed vowel works but only sometimes' points to an unreliable control mechanism. For professional TTS applications, precise stress control is non-negotiable for linguistic accuracy and natural speech synthesis. This recurring pain point suggests a fundamental gap in the model's phonetic control layer for complex languages. B2B SaaS providers must prioritize robust, explicit stress marking capabilities to ensure high-fidelity output and meet the demands of diverse linguistic markets.
