Provide common date/time formatting, locale voice matching, tone synthesis, phonetic spelling, and one hardware synthesizer protocol encoder for both readers. Standardize whiskey and x ray and use the tested Fenrir DECtalk mapping. Validated the common module with GOWORK=off go test -race ./...; reader integration, serial cancellation, PCM hashes, no-CGO datetime, and speech regression checks passed. Physical keyboard, audible synthesis, and braille acceptance remain separate live checks.
