Robert - I respectfully disagree. As a voice actor myself - you learn mic technique and that the microphone is there to amplify you... actresses like Bryna Raeburn and Evie Juster - even Marian Seldes had softer voices and were so wonderful on CBSRMT. Listen to Celeste in 'Wind and the Flame' or 'Mirror for Murder'... so naturally funny and so much layering as an actress. You are right in the early days of radio -- the radios needed strong voices as the sound was not as good ... but by the 50s - technology got better. Imagine Celeste in Sorry Wrong Number!! I don't think her focus was for radio but for theater and film. She actually played Anna in the King and I on Broadway at the Majestic Theater -- without a mic.. !! and did just fine... Radio was just not her focus.
