This API enables developers to create web applications with speech recognition features, where voice data is captured and processed on a remote server to produce text transcriptions. In practice, the results were somewhat inconsistent, with accuracy depending on factors like speaking volume and microphone quality. Despite early limitations, this technology hints at exciting future applications, such as speech-to-text services, voice-controlled web navigation, and enhanced accessibility for web users. Although still in its experimental stages, the Speech Input API represents a significant step toward making web apps more dynamic and user-friendly, especially on mobile devices.","ref_id":{"turn_index":0,"ref_type":"news","ref_index":33},"pub_date":1300896896,"attribution":"www.wired.com"}]},{"type":"search_result","url":"https://arxiv.org/abs/2508.05554","title":"SPGISpeech 2.0: Transcribed multi-speaker financial audio for speaker-tagged transcription","snippet":"","ref_id":{"turn_index":0,"ref_type":"academia","ref_index":34},"pub_date":null,"attribution":"arxiv.org"},{"type":"search_result","url":"https://www.wired.com/story/hospitals-ai-transcription-tools-hallucination","title":"OpenAI's Transcription Tool Hallucinates.

Whisper, which was released in 2022 and claimed to approach human-level accuracy, has been shown to fabricate or \"hallucinate\" text that was never spoken. Researchers and developers have discovered invented content in a large number of test transcriptsโup to 80% in one study.\n\nDespite OpenAI's warnings against using Whisper for โhigh-risk domains,โ over 30,000 medical workers across 40 health systems, including Mankato Clinic and Children's Hospital Los Angeles, use Whisper-powered tools by Nabla, which deletes original audio for data safety, further complicating the reliability of transcripts.\n\nBeyond healthcare, Whisper has been found to insert nonexistent and harmful content into audio transcriptions, including racial and violent statements, due to biases in its training data and its predictive nature. This behavior is attributed to the modelโs reliance on web-based, captioned audio content likely sourced from YouTube.\n\nExperts warn that Whisperโs use in critical domains could lead to serious consequences, urging stronger regulation and validation of AI tools to prevent harm from inaccurate AI-generated information.","ref_id":{"turn_index":0,"ref_type":"news","ref_index":36},"pub_date":1730289600,"attribution":"www.wired.com"},{"type":"search_result_group","domain":"www.lifewire.com","entries":[{"type":"search_result","url":"https://www.lifewire.com/otter-ai-french-spanish-transcriptions-8732706","title":"Otter.ai App Adds French and Spanish Transcription: What You Need to Know","snippet":"Otter.ai has expanded its capabilities by adding real-time transcription support for French and Spanish, in addition to English.

However, it does not offer translation services, so users must be fluent in the chosen language.\n\nThe app is free with a Basic plan offering 300 transcription minutes per month (30 minutes per conversation) and limits to three imported files. The Pro plan, costing $16.99/month or $100 annually, raises these limits to 1200 minutes per month, 90 minutes per conversation, and up to 10 imported files.
