Tape log
Text2Voice does not generate live speech through commercial APIs. Every playable file is either synthesized here from open models, or copied from a public vendor/paper demo and labelled as such.
Shared bench scripts (hook, narration, dialogue, news, numbers) were written for this site. They were rendered locally with eSpeak NG, Festival (kal diphone), Flite (slt), Piper (en_US-lessac-medium), Kokoro-82M (af_heart, int8 ONNX), Kyutai Pocket TTS (alba), and Meta MMS-TTS English (facebook/mms-tts-eng). Those seven engines are the fair comparison set.
Vendor and paper clips remain the property of their publishers. They are archived here for criticism, research, and comparison, with source URLs on every record. If you own a clip and want it removed, replace the file with silence and keep the catalog row — do not invent a substitute.
Do not treat a vendor demo as our bench line. The interface flags those clips in oxide red. Transcripts for documentation samples follow the publisher’s page where the sentence is printed; otherwise the caption says so.
