In their own words
iSpeech
iSpeech provides text-to-speech and automated speech recognition through APIs, SDKs, and online tools. Its speech API can synthesize audio with multiple voices, formats, bitrates, frequencies, and playback speeds, and supports MathML and SSML. The API can also transcribe submitted audio across multiple languages and recognition models; iSpeech says custom models can be created. The homepage lists support for more than 30 languages. Audio downloads are available in AIFF, MP3, OGG, WMA, FLAC, WAV, A-law, μ-law, VOX, and MP4 formats. Listed access includes Android, iOS, Linux, macOS, web, Windows, API, and extension. The Basic plan is free for personal use, and commercial use is listed as available. Plus costs $2.95 a month, billed monthly, and includes 30-minute recordings, approximately 4,167 words. Premium costs $3.95 a month, billed monthly, with 12-hour recordings, approximately 100,000 words. Pay Per Use costs $50 a month for dynamic TTS usage only and includes 2,000 credits. Pay Per Install costs $0.25 a month and has a 10,000-install minimum.
Oracle Cloud Infrastructure Speech
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.
