Oracle Cloud Infrastructure Speech vs Seed Audio

Oracle Cloud Infrastructure Speech transcribes submitted audio to text and synthesizes speech from text. Access is available through the OCI Console, REST APIs, CLIs, SDKs, and OCI Data Science notebook sessions. File-based asynchronous transcription is supported; real-time transcription is in limited availability. Transcription output defaults to JSON, with SRT also available at no additional cost. Tools include profanity filtering, punctuation, diarization, and word-level and full-transcription confidence scores. Supported audio includes single-channel 16-bit PCM WAV at 16 kHz, along with AAC, AC3, AMR, AU, FLAC, M4A, MKV, MP3, MP4, OGA, OGG, and WEBM. Oracle lists nine languages and says automatic language detection is not currently available. The first five transcription hours per month per tenancy are free; additional transcription or voice-synthesis hours cost $0.50 per hour, with usage aggregated in seconds. There are no setup charges, minimum commitments, or hardware requirements. Oracle says it retains no information from submitted files. Audio quality, accents, background noise, language switching, and simultaneous speakers can affect transcription quality.
