Challenges and Limitations

OpenAI's recent release of the gpt-4o voice AI models marks a significant stride in the realm of speech-to-text technology, yet it is accompanied by notable challenges and limitations. One of the primary issues is the absence of speaker diarization in the gpt-4o-transcribe models, which means the technology cannot differentiate between multiple speakers in a conversation. This limitation hinders usability in critical applications such as meeting transcriptions or customer service calls, where identifying speakers is crucial for accurate documentation [1](https://venturebeat.com/ai/openais-new-voice-ai-models-gpt-4o-transcribe-let-you-add-speech-to-your-existing-text-apps-in-seconds/).

Another challenge lies in the non-open-source nature of these models. Unlike OpenAI's Whisper model, which was available for broader community access and contribution, the new models limit accessibility for developers and researchers outside the proprietary ecosystem. This restriction may slow innovation and adaptation, particularly among small developers or in academic settings, where resources to access proprietary technology can be limited [1](https://techcrunch.com/2025/03/20/openai-upgrades-its-transcription-and-voice-generating-ai-models/).

While the models are priced competitively, allowing broader adoption, the consistency of their output remains a concern. Reports of inconsistent results, even with identical inputs, pose a risk for businesses that require reliable and predictable transcription for operational tasks. This inconsistency challenges the deployment of these models in environments where precision is paramount, underscoring the need for ongoing refinement and validation [4](https://opentools.ai/news/openais-new-audio-models-a-leap-toward-more-human-like-ai-voices).

Moreover, the absence of native support for certain language families, such as Indic and Dravidian languages, can limit the global applicability of the model. While these new voice AI models boast improved error rates and language recognition, their effectiveness remains biased towards predominant languages, potentially sidelining significant portions of non-English speaking populations [3](https://www.techzine.eu/news/devops/129823/openai-launches-new-speech-models-via-api/). Addressing this requires a concerted effort to expand linguistic capabilities to cater to the diverse global market.

The ethical implications of deploying these models cannot be overlooked, particularly concerning voice cloning and the creation of deepfakes. The customizability features of gpt-4o-mini-tts, which allow modifications in accent and tone, while innovative, also open doors to potential misuse. This includes the creation of synthetic voices for disinformation or fraudulent purposes, highlighting the pressing need for regulatory frameworks to govern the use of such technologies to prevent abuse [1](https://venturebeat.com/ai/openais-new-voice-ai-models-gpt-4o-transcribe-let-you-add-speech-to-your-existing-text-apps-in-seconds/).
