For those considering a move to NVDA 64-bit alphas or the upcoming beta and using ETI Eloquence 64-bit:
There is an issue with automatic language switching in multilingual HTML or MS Word content. When Eloquence 64-bit encounters the first non-default language (e.g. French), it switches correctly, but it does not switch back afterward. As a result, the remaining content is read using the wrong language voice.
This issue does not occur with eSpeak or SAPI 5 in NVDA 64-bit, nor with IBM TTS in NVDA 32-bit.
